iSeeCars data cited by InsideEVs says used EVs sold in an average of 41.9 days in September 2026, faster than used gas cars and hybrids. The Audi Q4 E-Tron Sportback, Toyota bZ4X and Lexus RZ 300e were the quickest-selling used EV models; no Tesla made the top 10. Used EV prices were up 9.8% year over year, though the report does not provide details on sample size or methodology.
Used electric vehicles sold faster than used gas cars in September 2026, averaging 41.9 days on dealer lots, according to iSeeCars data reported by InsideEVs. The quickest-selling used EV models included the Audi Q4 E-Tron Sportback, Toyota bZ4X and Lexus RZ 300e; no Tesla appeared among the top 10 fastest-selling models.
The report says the average time for a used EV to sell was 10.1% shorter than in September 2025. Used gas cars took an average of 54.8 days to sell, nearly two weeks longer than EVs, and their average selling time was up 19.9% year over year. The supplied report does not give a comparable selling-time figure for hybrids.
Prices also moved differently by drivetrain. Used EV prices rose 9.8% year over year in September, double the reported 4.8% increase for used hybrids. Used gas-car prices rose 0.3%. These are changes in average prices, not evidence that every vehicle in each category became more expensive.
Among the quickest-selling used EVs, the Honda Prologue, BMW iX and Polestar 2 also appeared on the list. At the other end, the Cadillac Escalade IQ was reported as the slowest seller, followed by the GMC Sierra EV, Chevrolet Silverado EV and Volvo EX90. The source does not provide the exact days-on-lot figures for each model.
Faster Sales, but a Narrower Market
The figures point to stronger sales momentum for used EVs in the period measured, which may matter to shoppers weighing an electric car against a conventional used vehicle. Faster turnover can signal that available buyers are moving more quickly, while the reported price gains suggest used EV values were not falling across the category in September.
But the comparison comes with an important supply caveat. The report says Autotrader listed 44,434 used EVs nationwide, compared with 1,384,383 used gas and diesel cars. That snapshot suggests buyers had far fewer used EVs to choose from, and the available EV models were also less numerous. Days on lot and price changes therefore describe a market with very different inventory levels, not a direct measure of equal demand across equally sized pools of vehicles.
The model rankings also complicate the assumption that Tesla dominates every part of the secondhand EV market. The fastest movers named in the report were from other brands. That could reflect buyer interest in particular vehicle types and prices, but the data provided do not establish why each model sold quickly.

September’s Price and Inventory Picture
InsideEVs attributes the figures to iSeeCars, which compared used-car prices and selling times by drivetrain and listed the fastest- and slowest-selling EV models for September 2026. The supplied report gives year-over-year comparisons against September 2025, rather than a longer trend line.
iSeeCars Executive Analyst Karl Brauer said the price changes reflected different year-over-year trends among drivetrains. He suggested higher fuel prices may have helped shift interest toward EVs, while saying the EV segment had also recovered from demand disruption tied to the loss of federal incentives a year earlier. Those are his explanations for the figures, not causal effects proved by the comparisons alone.
The report also notes that used prices for the Tesla Model S rose 22% and Model X prices rose 18% year over year, increases it describes as the largest among used cars regardless of powertrain. Price increases for those models do not explain why no Tesla made the fastest-selling top 10; the report does not provide a model-by-model account of that outcome.
What the Sales Figures Cannot Show
The source material does not include iSeeCars’ sample size, full methodology or model-level selling times. It also does not provide the number of transactions behind the averages or explain how vehicle age, mileage, trim and location were handled. Those details would help readers judge how broadly the results apply.
The reported comparisons show prices and days on lot, but do not by themselves prove that fuel costs caused more people to buy EVs, or that federal incentive changes drove the earlier demand disruption. Nor do they establish that the fastest-selling models are the most popular overall: limited inventory, pricing and local availability can affect how quickly a model sells. The report says used EV range degradation may be less severe than once thought, but the supplied material gives no study details or figures for that claim.
More Data Will Test the Trend
The next useful comparison will be whether later monthly iSeeCars reports show used EV selling times continuing to fall and whether the same models remain near the top of the rankings. Tracking inventory alongside selling times would help show whether rapid turnover reflects broader demand or limited supply.
For shoppers, the September figures are a market snapshot, not a guarantee about a specific vehicle’s value or condition. Buyers should compare asking prices, mileage, battery condition and local selection. The source material does not identify a scheduled follow-up report or say whether iSeeCars will publish additional model-level data.
Key Questions
How quickly did used EVs sell in September 2026?
They took an average of 41.9 days on the lot, according to iSeeCars data reported by InsideEVs. That was 10.1% faster than in September 2025.
Which used EVs sold fastest?
The Audi Q4 E-Tron Sportback led the list, followed by the Toyota bZ4X and Lexus RZ 300e. The report also named the Honda Prologue, BMW iX and Polestar 2 among the fastest sellers, but did not provide exact model-level selling times.
Did any Tesla make the fastest-selling top 10?
No. The report says no Tesla model appeared among the top 10 fastest-selling used EVs for September 2026. It does not give a detailed explanation for the ranking.
Were used EV prices rising?
Yes. Average used EV prices were reported up 9.8% year over year in September 2026. The same report gave increases of 4.8% for hybrids and 0.3% for gas cars.
Do these figures prove that fuel prices caused the shift?
No. iSeeCars analyst Karl Brauer said higher fuel prices were likely driving the shift, but the reported price and selling-time comparisons do not prove that cause. The source also does not include the methodology needed to assess other factors.
