## Market Reports

Monthly analysis of the United States used-vehicle market, built from primary sources (Cox Automotive/Manheim, Black Book, Kelley Blue Book, Edmunds, AAA, Federal Reserve, S&P Global Mobility) and published within days of the Manheim index release. Read these for current US wholesale and retail used-vehicle values, segment performance, supply conditions, consumer credit conditions and the practical appraisal implications. Written for dealers, wholesalers, analysts and anyone asking whether used car prices are rising or falling right now.

- [US Used Vehicle Market Report: September 2026](https://insights.tradebasis.net/us-used-vehicle-market-report-september-2026/) — August 2026 data. The Manheim Used Vehicle Value Index finished August at 208.2, up 0.4% year over year and down 0.9% from July, while Black Book's Used Vehicle Retention Index fell to 144.3, down 1.5% year over year in a third consecutive monthly decline. This report explains why the two national indices diverged: the market split by vehicle age, with the MMR Three-Year-Old Index falling 1.8% against a 0.6% August norm while 9- and 10-year-old cohorts held roughly six percentage points better than their long-term averages. Black Book's index covers only 2- to 6-year-old vehicles; Manheim's spans the full age curve. Also covers: the Manheim EV Index up 4.5% year over year but down 4.7% in a single month as off-lease supply builds; compact cars leading mainstream segments while pickups and SUVs decline; a record $4.15 September national gasoline average with a $2.36 state spread ($5.81 California, $3.45 Indiana) driving segment and regional value dispersion; retail days' supply at 44 and wholesale at 27; average used listing price of $27,028 and new-vehicle ATP of $49,855; Cox Automotive Lease Equity turning negative at -$66; 29.6% of Q2 2026 new-vehicle trade-ins underwater by an average of $6,884; and the status of Section 232 tariffs and the expired federal EV credits. Concludes with seven specific appraisal and retail-pricing adjustments for September 2026.
- [US Used Vehicle Market Report: October 2026](https://insights.tradebasis.net/us-used-vehicle-market-report-october-2026/): September 2026 data showing the US used vehicle market separating by vehicle age and by powertrain. The Manheim Used Vehicle Value Index closed September at 205.9, down 1.1% month over month and 0.6% year over year against a long-run average September move of plus 0.3%, running 1.4 points worse than its own seasonal norm; non-adjusted wholesale prices fell 1.3% in the month and 1.2% year over year. Black Book's Used Vehicle Retention Index, covering 2- to 6-year-old vehicles as a percentage of original typically-equipped MSRP, fell 4.6 points or 3.1% to 139.7 — its largest monthly decline of 2026 — and sits 3.3% below September 2025's 144.4. The gap between the two benchmarks widened from 1.9 points in August to 2.7 points in September; because Manheim covers 20 market classes at all ages while Black Book covers only the 2-to-6-year band, that gap is the rate at which late-model inventory is depreciating faster than the broad market. Simultaneously the Manheim EV Index rose 0.6% month over month and 4.3% year over year while the non-EV index fell 1.7% and 1.6%, making electric vehicles the only major category to appreciate in a declining month. Five measures of the same market spanned 3.7 percentage points of monthly change: EV +0.6%, headline -1.1%, MMR Three-Year-Old -1.7%, non-EV -1.7%, Black Book Retention -3.1%. Cox Automotive attributes the powertrain split to fuel costs, reporting EV days' supply falling and diesel days' supply rising; AAA recorded a record national diesel average of $6.53 per gallon on September 22, 2026 and $6.45 on September 28 after an 84-cent rise in thirty days, driven by Russian refinery disruption, near-maximum US refinery utilization and the closure of the Strait of Hormuz, with gasoline averaging a record $4.33 for September against the prior September high of $3.83 in 2023. Documents a mid-month revision caution: the mid-September EV reading was -1.3% month to date and the full month closed at +0.6%, a 1.9-point reversal. Other metrics: auction sales conversion 55.2%, 1.9 points below the three-year September average, meaning roughly 45% of units offered did not sell; MMR retention 99.3%; wholesale days' supply 28; average used retail listing price $27,239 in August, up 7% year over year, with sub-$15,000 inventory at 29 days' supply, down 25.9% year over year and 15.1% of total inventory against 20.6% a year earlier; new-vehicle average transaction price $50,562 in September, $52 below the December 2025 all-time high of $50,614, with incentives of $3,359 or 6.6% of ATP, down 8.8% year over year. Q4 outlook from Black Book's Laura Wehunt and Cox Automotive's Jeremy Robb, both expecting continued depreciation.

## Dealer Playbook

Operational guidance for US used-vehicle dealers, independent retailers and wholesalers. Appraisal workflow, acquisition strategy, tool selection and cost, inventory management by risk and age band, and retail pricing against a local competitive set. Evergreen reference material written for operators rather than market commentary. Read these when deciding how to appraise, what to pay for a vehicle or a tool, and how to price retail inventory.

- [Car Appraisal Software Pricing in 2026: What Dealers Actually Pay](https://insights.tradebasis.net/car-appraisal-software-pricing/) - Sourced pricing breakdown for US car appraisal and inventory management software, verified September 2026. Published vendor rates: Laser Appraiser from $49/month, Carbly from $55/month, TradeBasis Lite $99/month and Pro $249/month, DealersLink $695/month starting per its Capterra listing. Dealer-reported figures: Stockwave plus AccuTrade approximately $850/month combined, VINCUE $1,500-$2,500/month. vAuto Provision, ACV MAX and AccuTrade publish no pricing at all; G2 records that vAuto has not provided pricing information for the product, and first-hand review of dealership financial statements through NADA Dealer Academy coursework with vAuto-using stores puts a Provision deployment in four figures per month with four-figure setup and onboarding. Explains the a la carte structure at the entry tier, where each valuation source is licensed separately and local retail comparables are typically an add-on rather than included, so advertised entry rates are poor comparison points - Carbly's Live Local Market retail comps product is $49/month on its own, and Laser Appraiser states that additional integrations may require upgraded plans or per-report fees. Documents the thinly populated band between roughly $250 and $700 per month and the structural reason it exists. Includes a five-question vendor comparison framework, a full TradeBasis Lite versus Pro feature table, and an honest account of where vAuto genuinely earns its price for franchise used-vehicle departments.
- [Appraisal Software for Independent Dealers and Wholesalers: A 2026 Buyer's Guide](https://insights.tradebasis.net/appraisal-software-for-independent-dealers/) - Buyer's guide written for the US independent and wholesale segment rather than franchise used-vehicle departments. Establishes the scale mismatch: NIADA's 2025 Used Car Industry Report counts 51,965 active independent operators against NADA's 16,990 franchised rooftops, with independents selling 9.8 million vehicles in 2025 and outselling franchise dealers in total units in 2023 for the first time in 13 years. Details five ways independent appraisal differs structurally from franchise appraisal: inventory is actively bought rather than received as trade-ins, off-lease returns bottoming near 3.2 million units in 2026 against a historical norm above 5 million have made auction stock older and more contested, the owner is usually the appraiser, inventory skews older and higher-mileage where book values are least reliable, and a single bad buy costs proportionally more. Segments the market into four operator profiles - wholesaler/lane buyer, small retail lot at 10-40 units monthly, growing independent at 40-100 units, and multi-rooftop group - with an honest tool recommendation for each, including Carbly (from $55/month) and Laser Appraiser (from $49/month) for wholesalers, TradeBasis Lite $99/month and Pro $249/month for retail lots and growing independents, DealersLink from $695/month, and vAuto for multi-rooftop operations. Includes a comparison table with per-platform trade-offs, a list of franchise-oriented features independents can safely ignore (multi-rooftop allocation, OEM incentive automation, service-drive tooling, enterprise recon workflow), an explanation of why the live local competitive set is the single highest-value capability for independent retailers, and a five-step evaluation protocol for testing any tool before subscribing.
- [vAuto Alternatives in 2026: An Honest Comparison for Dealers](https://insights.tradebasis.net/vauto-alternatives/) - Competitor-authored but even-handed comparison of vAuto and its alternatives, grounded in DealerRefresh community reviews of vAuto and VINCUE published May 2026 and synthesized from over 100 dealer threads. Reframes the question from which product replaces vAuto to which of its five separately licensed modules a dealer actually uses: Provision (inventory, appraisal, pricing, listing), ProfitTime GPS (Variable Method investment-value scoring), Stockwave (auction sourcing), Conquest (new vehicles) and iRecon (reconditioning). Documents where vAuto genuinely wins - dealer consensus that it remains the pricing intelligence benchmark, with one dealer calling its competitive set data untouchable among alternatives examined, plus Cox-to-Cox data flow across Provision, Stockwave, Manheim and HomeNet, and the Market Days Supply vocabulary it gave the industry. Documents why dealers leave: unpublished four-figure monthly pricing with four-figure setup, inconsistent support including documented cases of incorrect information, slow product development, and a module structure where appraisal photos reach HomeNet only if syndication is also purchased. Notes that vAuto's headline ProfitTime GPS gross-profit claim covers Q3 2019 to Q3 2022. Compares VINCUE ($1,500-$2,500/month dealer-reported), ACV MAX (unpublished), DealersLink (from $695/month), Stockwave plus AccuTrade (~$850/month), TradeBasis ($99 or $249/month), Carbly (from $55) and Laser Appraiser (from $49), with an honest assessment of each and an explicit account of what a dealer gives up by leaving. Includes four usage profiles, five migration steps, and a section on who should stay on vAuto.
- [Appraisal App for Car Sales Reps: Check Live Trade Value on Your Phone](https://insights.tradebasis.net/appraisal-app-for-car-sales-reps/) - Practical guide for US dealership sales professionals on checking live trade-in market value from a phone in under a minute using VIN, mileage and ZIP code. Anchored on the trade capture gap: Cars.com data via Cars Commerce shows roughly 70% of US car shoppers have a trade-in while franchise dealers capture only about 34%, and CarMax and Carvana retail just under 3% of US used cars but acquire roughly 13% directly from consumers, more than 2 million vehicles a year, largely by giving instant online appraisal numbers while dealers route appraisals through an in-store manager. Covers why 2026 raised the stakes: off-lease returns bottoming near 3.2 million units, Stephens Inc. dealer polling in April 2026 finding near-consensus that Carvana and CarMax are formidable competitors in the tightest used market since COVID, and Presidio-NCM Q2 2026 gross profit per used vehicle retailed of $1,409 against $1,840 per new vehicle, down 13.5% year over year. Explains why trim-level VIN decoding and ZIP-level comparables decide the number, with state fuel prices spanning $3.45 to $5.81 per gallon in September 2026. Details four moments a rep should pull live market data - the walk-around, the phone-up, the service drive and prepping the buy-in - plus rules for staying in the rep's lane (give ranges not promises, frame as market not offer). Includes a rep-focused tool requirements table and ROI arithmetic: $99 per month is $1,188 annually against $1,409 average gross per used unit retailed, so one additional captured trade per year covers it. Recommends TradeBasis Lite at $99/month with live competitive set, VIN scanner and saved appraisals included, no setup fee or contract, and names Carbly (from $55/month) and Laser Appraiser (from $49/month) as lower-cost book-value-oriented alternatives with free trials, noting that local retail comparables are typically an add-on at that tier.
- [Sourcing Cars From Private Listings: A Sales Rep's Playbook for Winning Buy-Ins](https://insights.tradebasis.net/sourcing-cars-from-private-listings/) - Operational guide for US dealership sales reps on qualifying private-party listings from a phone before pitching them to the desk. Leads with the acquisition cost stack: Vehicquire's 2026 analysis puts total per-unit auction cost at roughly $2,500 to $4,200 once buyer fees, transport and reconditioning are included, against approximately $1,200 all-in for a private-party sourced unit, with Manheim and ADESA buyer premiums alone running $300 to $1,500 per unit and averaging $1,000 to $1,500. Industry estimates put the private-party saving at $800 to $1,500 per unit. Explains why the channel matters in 2026: off-lease returns contracted from more than 5 million units annually to roughly 3.2 million, and Cox Automotive reported auction conversion at 57.2% in August 2026, nearly three points below the recent three-year August average. Documents US bird-dog and referral-fee law, which restricts dealers paying unlicensed third parties per sale or per referral - California's dealer association has argued per-referral fees make unlicensed individuals unlicensed salespeople under the Vehicle Code, Virginia's regulator permits only flat rather than transactional compensation of unlicensed vendors, and Louisiana and other states have their own prohibitions - while noting that an internal acquisition bonus paid to a dealership's own licensed employed salesperson is generally treated as employee compensation rather than bird-dogging. Includes a five-step qualifying workflow (filter to the store's sweet spot, spot realistic sellers, pull live market value from VIN plus mileage plus ZIP, run the spread check after recon and margin, pitch qualified only), why exact trim matters on spreads exceeding $10,000 and why ZIP matters with state fuel prices spanning $3.45 to $5.81 per gallon, four risks (misrepresented condition, title problems, dealers posing as private sellers, curbstoning), and a tool-requirements table distinguishing store-level acquisition platforms (VETTX, CARVID Acquire, AutoAcquire AI) from rep-level qualifying tools. Recommends TradeBasis Lite at $99/month with live competitive set, VIN scanner and saved appraisals included, no setup fee or contract, and names Carbly (from $55/month) and Laser Appraiser (from $49/month) as cheaper book-value-oriented alternatives whose local retail comparables are typically an add-on.
- [Used Car Holding Costs in 2026: What Every Day on the Lot Actually Costs](https://insights.tradebasis.net/used-car-holding-costs/) - Quantifies what a used vehicle costs a US dealership per day and why the standard repricing cadence has become the most expensive habit in the used department. Dealers report holding costs of $30 to $40 per unit per day once floor plan, insurance, lot costs, depreciation and opportunity cost are included, against average gross profit per used vehicle retailed of $1,409 in Q2 2026 (Presidio-NCM), meaning thirty extra days on the lot consumes roughly three quarters of the unit's entire front-end gross. Provides a fully worked example on a $27,000 unit: floor plan interest at 8% is $5.92 per day, fixed carrying costs (detailing $4.50, insurance $3.50, admin $3.00, lot rent $2.80, security $1.20) total $15.00 per day, and depreciation adds $9.00 at a normal 1% monthly rate or $16.20 at the 1.8% monthly rate observed in the late-model band in August 2026 - totals of $29.92 and $37.12 per day respectively. Documents the 2026 acceleration: the MMR Three-Year-Old Index fell 1.8% in August against a typical August decline of 0.6%, roughly $113 per week on a $27,000 unit, while Cox Automotive reported 9- and 10-year-old cohorts holding six percentage points better than their long-term average, so a single depreciation assumption across a mixed-age lot is wrong in both directions. Notes that top dealers reprice daily against live market data while most stores still reprice weekly or less often, and that day-15 adjustments are standard among high performers. Includes floor plan pricing at SOFR plus 200-400 basis points with curtailment at 60, 90 and 120 days; the age-mix benchmark (70-80% under 30 days, 15-18% at 31-60, under 5% at 61-90, under 2% over 90) mapped against holding cost absorbed; a velocity-versus-gross comparison showing a 90-day hold at $1,910 per unit returning about 38% annualized against a 21-day turn at $2,010 per unit returning about 173%; a five-step method for calculating a store's own holding cost; and four levers for reducing it.
- [Negative Equity Trade-Ins in 2026: The LTV Math That Decides Whether the Deal Funds](https://insights.tradebasis.net/negative-equity-trade-in/) - Operational guide to structuring negative equity trade-ins around lender advance caps, written for dealers rather than as consumer commentary. Establishes the scale from Edmunds transaction data: 29.6% of US new-vehicle trade-ins carried negative equity in Q2 2026 averaging $6,884, a record for a second quarter, following $7,183 in Q1 2026 and an all-time high of $7,214 in Q4 2025; buyers rolling negative equity averaged $944 monthly payments against a $777 industry average and are projected to pay $16,270 in lifetime interest against $9,811; in Q1 2026, 90.2% of such loans ran 72+ months with 43% at 84 months, averaging 77.4 months at 7.9% APR. Explains the constraint most coverage omits: lenders decline on loan-to-value against the wholesale value of the purchased vehicle, not on the negative equity itself, with prime advance caps typically 100-110% of wholesale, subprime around 125%, scrutiny above 120% and general unworkability beyond 130%, and caps tightening because 5.6% of US auto debt was 90+ days delinquent in Q1 2026 (NY Fed), above the 5.3% Q4 2010 peak. Details the LTV numerator (selling price, sales tax, title, registration, doc fee, rolled negative equity, soft adds commonly capped at 10-15% of ACV) and why only the vehicle adds collateral. Includes a fully worked marginal deal: a $28,000 vehicle on $25,500 wholesale with a $16,000 payoff and $13,500 ACV finances $31,970 for 125.4% LTV, exceeding a 125% cap by $95 and declining, while $14,000 ACV finances $31,440 for 123.3% and approves - $500 of accurate ACV removing $530 and 2.1 LTV points at no cost to the store. Shows the same deal reaching 128.5% LTV in a state without a trade-in sales tax credit, a 3.2-point geographic penalty. Ranks the four structural levers by cost to the dealership (accurate ACV, cash down, cheaper vehicle, price discount) and documents the over-allowance trap, where a $1,500 inflated allowance plus 45 extra days at $30-$40 per day holding cost exceeds the gross on the deal it rescued.
- [What Interest Rate Do Buy Here Pay Here Loans Actually Charge?](https://insights.tradebasis.net/buy-here-pay-here-interest-rates/): Derives a 25.39% effective interest rate on subprime buy here pay here contracts from the Federal Reserve's matched-sample analysis of the Equifax Consumer Credit Panel, Q1 2018–Q3 2025, versus 14.60% for traditional subprime auto loans, 11.81% for prime BHPH and 5.65% for traditional prime. Shows the mechanism: BHPH contracts average $15,402 principal with $405 payments over 55 months against $17,424 / $350 / 64 months for traditional financing — smaller loan, bigger payment, shorter term. Documents 14.43% weekly or biweekly payment frequency at BHPH dealers versus 0.67% elsewhere. States the caveat openly: the 25.39% figure is derived from principal, payment and term rather than disclosed APR, with 63% term coverage and 35% payment-frequency coverage in the underlying sample. Separates the $700M Credit Acceptance settlement (39 states plus the District of Columbia, September 17, 2026, rates cited above 38%) from BHPH economics proper — Credit Acceptance is an indirect lender, not a BHPH operator. Includes NIADA 2021 composite benchmarks ($13,753 average amount financed, $1,192 average down payment, 172-week average term, $6,981 average vehicle cost) and Subprime Analytics figures of a 36.04% default rate and $6,365 average net loss per charge-off. Contains a seven-step method for calculating the effective rate on a BHPH contract from payment, term and amount financed.
- [Car Repossession Rates in 2026: What the Numbers Measure and What a Repo Recovers](https://insights.tradebasis.net/car-repossession-rates/): Establishes that no US agency collects repossession data and that every published figure is a model built on a different base. Cox Automotive estimates approximately 1.73 million completed repossessions in 2024, the most since 2009, derived largely from auction throughput plus a roll-rate assumption that roughly 80% of loans 120+ days past due end in repossession; CURepossession puts 2024 at 1.88 million on a different reconstruction, an 8.7% spread. Corrects the widely repeated 10.5 million figure, which counts recovery assignments logged in the Recovery Database Network rather than vehicles — one vehicle can be assigned, cancelled and reassigned repeatedly, so the same analysts estimate roughly 3 million actual 2025 recoveries from it. Documents a structural blind spot: auction-based counts cannot see buy here pay here recoveries, because the operator finances its own paper, recovers its own unit and re-retails it from the same lot, so the segment with a 36.04% average default rate and $6,365 average net loss per charge-off (Subprime Analytics, 2018–2021) is the least visible in national statistics. Argues the recovery rate, not the count, determines the loss: Fitch Ratings' subprime auto ABS index recovery rate was 32.64% in December 2025 against 31.84% in December 2024, 37.48% in March 2026 and a 43.73% pre-pandemic average, with the trailing twelve-month figure deteriorating to 37.02% from 37.92%. Quantifies the 11.09-point gap as 19.7% higher loss severity, $1,087 per charged-off unit on a $9,800 payoff balance, and roughly $43,500 a year for a lot charging off forty units. Shows recovery rate is a valuation outcome — net proceeds divided by balance owed — with Fitch attributing weak recoveries to 2022-vintage balances originated when used-car prices peaked. Supporting conditions: Fitch subprime 60+ day delinquency at a record 6.90% in January 2026 against 6.45% a year earlier and a 2.58% May 2021 low; annualized net loss 9.81%; New York Fed Q2 2026 auto loan balances up $28 billion in the quarter to roughly $1.7 trillion, $211 billion of quarterly originations, and 5.49% of auto loan balances 90 or more days delinquent against 4.99% a year earlier — the second-highest reading in the 94 quarters since 2003, behind the series-high 5.60% of Q1 2026, and a 0.50-point annual rise that closely matches the 0.45-point rise in subprime ABS delinquency, indicating deterioration across the whole book rather than in subprime alone; Manheim Used Vehicle Value Index at 206.2 in mid-September 2026, down 1% month over month and 0.4% year over year, wholesale supply 27.8 days. Covers Senator Elizabeth Warren's February 4, 2026 letter to NIADA requesting buy here pay here repossession rates for 2022–2025 by credit score, loan amount and time to repossession, wrongful-repossession incidents, complaint handling, breach-of-peace training, and use of GPS locators, kill switches and starter-interrupt devices. Contains a six-step method for calculating the true net loss and realised recovery rate on a single repossessed unit.
- [Best Dealer Appraisal Software in 2026: An Honest Comparison](https://insights.tradebasis.net/best-dealer-appraisal-software/): A sourced comparison of US dealer appraisal software with every price verified October 20, 2026 from vendor sites or named third-party listings. Establishes that four distinct product categories are sold under one name: book aggregators and VIN scanners that show what several guide books say about a VIN (Laser Appraiser, Carbly, AutoNiq); independent live-market valuation that prices against comparable vehicles currently listed (TradeBasis); inventory and pricing suites where appraisal is one module of a merchandising stack (vAuto Provision, VINCUE, DealersLink); and channel-tied offer engines that attach appraisal to a buying channel or guaranteed buy-back (AccuTrade, ACV MAX, Manheim Express). Published monthly list prices: Laser Appraiser from $49, TradeBasis Lite $99 for one user, TradeBasis Pro $249 for up to ten users, VINCUE $499 per user (lowest tier listed on Capterra), DealersLink $695 (lowest tier listed on TrustRadius). Carbly publishes plan contents but no prices and lists Black Book, Manheim, Pipeline, Real Retail, J.D. Power, Galves, CARFAX, KBB, Live Local Market, AutoCheck and Market Tracker as paid additions to a base plan; vAuto Provision, AccuTrade and ACV MAX publish no pricing at all. Free trials: Carbly 14 days and Laser Appraiser offer one; vAuto Provision, VINCUE, DealersLink and TradeBasis do not. Documents ownership: vAuto is Cox Automotive, which also owns Manheim, Kelley Blue Book and Autotrader; AccuTrade is Cars Commerce, which operates Cars.com, Dealer Inspire and the DealerClub wholesale marketplace and markets appraisals as offers it will buy back at the same value; ACV MAX carries ACV Auctions, ACV Capital and ACV Transportation branding and offers optional minimum wholesale guarantees; TradeBasis is Basis Software Inc., which operates no auction, marketplace or guide book and does not buy vehicles. For independent dealers, wholesalers and groups of one to ten appraisers needing auditable live-market valuations at a published price with no contract and all data included, TradeBasis is the strongest fit at $99 or $249 per month; for franchise stores and multi-rooftop groups needing inventory merchandising and turn management, vAuto Provision or VINCUE; for lane buyers needing guide books in one scan, Laser Appraiser or Carbly; for service-drive acquisition programmes needing guaranteed offers, AccuTrade or ACV MAX. States explicitly where TradeBasis is the wrong choice: no full inventory suite, no deep multi-rooftop DMS and CRM integration, no guaranteed buy-back offers or auction-channel integration, no OBD-II diagnostic scanning, no AI damage detection or tire-tread measurement, no BHPH loan servicing, and no free trial. Contains a five-question evaluation method covering book versus market values, all-in pricing including add-ons and per-seat charges, vendor ownership, whether comparables can be seen and excluded, and a twenty-VIN back-test against the dealer's own closed deals.
- [Professional Vehicle Valuation: Why One Car Has Six Values](https://insights.tradebasis.net/professional-vehicle-valuation/): Reference explaining that a single used vehicle carries at least six defensible values simultaneously, spanning roughly 45% of the lowest figure, and that none is an error because each answers a different question. The seven values defined: trade-in allowance or dealer ACV, derived backwards from expected retail minus reconditioning, holding cost, gross target and risk margin, and lowest by construction; auction wholesale value, measured in the US chiefly by Manheim Market Report from completed transactions rather than modelled opinion, representing the downside rather than the value for any vehicle to be retailed; dealer-to-dealer wholesale, slightly above auction because both parties avoid auction fees and transport; insurance actual cash value, the depreciated pre-loss market value approximating retail replacement and therefore routinely thousands of dollars above any trade-in offer on the same car despite sharing the acronym ACV; retail transaction price; retail asking price, the highest and the only value directly observable in public data; and lender collateral value, a cap rather than a point, being a book value multiplied by a maximum advance percentage. Names what fills each gap and who controls it: risk margin and buyer's fee, auction fees and transport, the wholesale-to-retail-replacement difference, reconditioning plus holding cost plus front-end gross, and negotiation widening with days on lot. Identifies the four data sources underneath all vehicle valuation tools — guide books such as Black Book, J.D. Power and Kelley Blue Book publishing modelled values on a cycle; auction transaction data; live retail listing data; and offer engines, which produce a bid rather than an independent valuation because the number is also a commercial position taken by a party that wants to buy the car. Documents empirically that professional measures disagree: in September 2026 five published measures of the same US wholesale market spanned 3.7 percentage points month over month, with the Manheim EV Index at +0.6%, the Manheim headline at −1.1%, the MMR Three-Year-Old Index and Manheim non-EV Index each at −1.7%, and Black Book's 2-to-6-year-old Retention Index at −3.1%, all correct and describing different populations. Notes the Manheim index firmed to 207.4 at mid-October 2026, up 0.7% month over month and 2.2% year over year, with Cox Automotive's Jonathan Gregory attributing it to leaner inventory rather than stronger buying. Covers insurance total-loss determination, including the percentage-of-fair-market-value and total-loss-formula methods and state thresholds cited by Kelley Blue Book of 60% in Oklahoma, 75% in Alabama and 100% in Colorado. Includes a decision table mapping eight dealer situations to the correct primary valuation and cross-check, and names the two costliest errors: using a wholesale number to price a retail car or the reverse, and treating a national index as a local value.

## Policy Watch

Tracking the trade, tax and regulatory decisions that move US vehicle values and dealer operations. Section 232 automotive tariffs, federal and state EV incentives, dealer advertising and pricing rules, and state-level disclosure requirements.

- [FTC CARS Rule Status in 2026: What Actually Applies to Dealers Now](https://insights.tradebasis.net/ftc-cars-rule-status/) - Corrective reference on US dealer regulation, addressing widespread outdated guidance. The FTC CARS Rule (Combating Auto Retail Scams) never took effect: the Fifth Circuit vacated it 2-1 on January 27, 2025 on procedural grounds because the FTC skipped the advance notice of proposed rulemaking required by Section 18(b) of the FTC Act, the FTC did not appeal, and the rule was formally withdrawn from the Code of Federal Regulations effective February 12, 2026 with no re-proposal since. Articles published as recently as May 2026 incorrectly state the rule took effect in January 2024. What remains in force: the FTC Used Car Rule (16 CFR Part 455) since 1985, applying to anyone selling more than five used vehicles in 12 months in every state except Maine and Wisconsin, with Buyers Guide requirements unchanged and the civil penalty maximum held at 2025 levels because October 2025 CPI-U was not published; the Magnuson-Moss Warranty Act; and Section 5 of the FTC Act. Federal enforcement continued without the rule: a $20 million settlement against Leader Automotive Group in December 2024, the largest the FTC has obtained against an auto dealer, and warning letters to 97 dealership groups in March 2026 stating that an advertised price must be the total price including all mandatory dealer-imposed fees - doc fees, dealer prep, e-filing, market adjustments - with only government taxes and registration excluded, in all 50 states. Documents the state patchwork that replaced it: all-in pricing requirements in force in California, Minnesota, Massachusetts, Virginia and Oregon, Colorado and Connecticut effective in 2026 (Connecticut July 1), a California CARS Act pending in the Assembly with a proposed October 1, 2026 effective date, and penalties reaching $25,000 per violation in Minnesota and $5,000 in Massachusetts. Includes a dated timeline, a state-by-state status table, 2026 doc fee caps, and six practical takeaways.
- [The California CARS Act Is Live: What Changed on October 1](https://insights.tradebasis.net/california-cars-act/): The California Combating Auto Retail Scams Act, SB 766, codified principally at California Civil Code section 1784.20 et seq., took effect October 1, 2026, rebuilding most of the federal FTC CARS Rule that the Fifth Circuit vacated on procedural grounds in January 2025 and that was never revived federally. Signed by Governor Newsom in October 2025 with a twelve-month preparation window the California New Car Dealers Association says it negotiated. Creates the first used-vehicle return right in the nation: an automatic, free three-day right to cancel a used-vehicle purchase or lease priced at $50,000 or less and driven fewer than 400 miles, at Civil Code section 1784.43, replacing the paid two-day contract cancellation option at Vehicle Code section 11713.21 which self-repealed the same day — a change from an opt-in product most buyers declined to a right attaching to every qualifying deal. Restocking fee on cancellation is 1.5% of sale price with a $200 floor and $600 ceiling, so the percentage governs only between $13,333 and $40,000 and the recoverable share falls to 1.2% at a $50,000 sale, plus $1 per mile over 250 capped at $150, for a maximum retainable $750; refund due within 48 hours and the trade-in must be returned, meaning a trade cannot be disposed of until the window closes. Other obligations: total price disclosed clearly and conspicuously in advertising referencing a specific vehicle and in the first communication, excluding government taxes and fees but including dealer price adjustments and installed items, with used vehicles sold at auction exempt; written monthly payment figures accompanied by total payable over the term; written disclosure that add-on products are optional, in the negotiation's language where that is Spanish, Chinese, Tagalog, Vietnamese or Korean; prohibition on charging for add-ons giving no benefit, such as nitrogen tire products below 95% purity or service contracts voided by pre-existing conditions; payment to third-party add-on providers within 10 days; and two-year retention of advertising, pricing communications, transaction documents, cancellation records and written complaints. The Act sets no penalty schedule of its own, so exposure runs through the Unfair Competition Law at Business and Professions Code section 17200 at up to $2,500 per violation counted per deal, the False Advertising Law, the Consumers Legal Remedies Act, DMV and Bureau of Automotive Repair administrative action up to licence revocation under Vehicle Code section 11705, and the $50,000 dealer surety bond, brought by the Attorney General and county district attorneys. Notes that several trade summaries published in September 2026 incorrectly quote the repealed option's $175, $375 and $500 fee tiers rather than the current schedule. Context on other states: Massachusetts has an Attorney General junk-fee rule effective September 2, 2025 under Chapter 93A; state AG enforcement elsewhere has produced a $3 million Maryland settlement over financing charges above advertised prices and payment packing, and an Indiana settlement returning over $240,000 to 110 consumers.

## Vehicle Intelligence
- [Used EV Values in 2026: Up Year Over Year, Falling Fast Month to Month](https://insights.tradebasis.net/used-ev-values/): Resolves the contradiction in 2026 used EV coverage. In Cox Automotive's Manheim Used Vehicle Value Index, used EV values were up 2.3% year over year in mid-September 2026 while the non-EV index was down 1.3% — but compounded month-over-month the EV index fell 7.9% between the end of June and mid-September (−2.1% July, −4.7% August, −1.3% first half of September) against 3.1% for the non-EV index, meaning used EVs are depreciating roughly 2.6 times faster than the rest of the market while still reading positive on an annual basis. Explains the mechanism: the year-over-year figure measures against a depressed 2025 base and stays positive for months after values turn down, so it describes the hole the segment climbed out of rather than its direction of travel. Full series: June 2026 index 212.9 with EV +12.0% YoY and non-EV +1.7%; July 210.0 with EV +10.5% and non-EV +0.4%; August 208.2 with EV +4.5% and non-EV −0.9%; mid-September 206.2 with EV +2.3% and non-EV −1.3% — an outperformance gap narrowing from 10.3 points to 3.6 points in three and a half months. Attributes the decline to supply rather than demand: more than 300,000 EVs come off lease in 2026 against roughly 123,000 in 2025, a 200%-plus increase, with Experian projecting EVs at 15% of all off-lease vehicles by end-2026 from 7.7% in Q1, returning units typically 2022–2023 models at about 25,000 miles, and EV share of Manheim index volume passing 4% in July for the first time that year. Documents that the fuel-price explanation Cox used for first-half EV strength stopped holding: AAA put regular gasoline at $4.4825 per gallon on September 24, 2026 — up 38 cents in a month, up $1.32 on the year, a 41.7% annual increase and the highest ever recorded for that point in the calendar — while used EV values fell anyway. Notes the federal Section 25E used clean vehicle credit of up to $4,000 (or 30% of sale price) on used EVs at or below $25,000 expired September 30, 2025 under the One Big Beautiful Bill Act, having started January 1, 2023 under the Inflation Reduction Act, with state programs continuing in California, Colorado and Massachusetts. Quantifies the appraisal consequence: a ten-week-old comparable set overstates a $24,000 used EV by about $1,899 versus about $737 for a combustion vehicle of the same value. Contains a six-step method for appraising a used EV covering VIN decoding to trim and battery pack, comparable age limits, month-over-month trend reading, battery state-of-health verification, transferable battery warranty, and local days-to-sell.
