Used-Vehicle Inventory Sets New High for 2025 as Sales Continue to Climb

Used-vehicle inventory levels rose at the start of September, marking the highest point so far in 2025, according to the Cox Automotive analysis of vAuto Live Market View data.

Nationwide, dealers – both franchised and independent – had a total supply of 2.21 million used vehicles on their lots at the beginning of September. That figure was 2% higher than the 2.16 million in early August and remains 2% higher than the same time last year.

The retail used-vehicle sales pace was up nearly 5% month over month in the most recent 30-day period. Used retail sales were at 1.55 million vehicles in August, up from the 1.48 million reported in July. Sales have maintained strong momentum in the second half of the year as pent-up demand enters the market, with previously sidelined buyers seeing this as a relatively favorable window compared to recent years to purchase a vehicle amid improved conditions and uncertainty about the future. The used market especially benefits from consumers seeking more affordable alternatives than those offered in the new car segment. Sales continue to outperform recent years, with an 8% increase in August compared to the previous year.

USED-VEHICLE INVENTORY VOLUME AND DAYS’ SUPPLY

The Cox Automotive days’ supply is based on the estimated daily retail sales rate for the most recent 30-day period. Used vehicles had 43 days’ supply at the start of September, down one day from the upwardly revised level at the beginning of August and down two days compared to the same time last year. Days’ supply continues to be constrained, remaining below levels seen in recent years. Days’ supply remains the lowest it has been in three years for this time of year, as well as the same time in 2019.

Used retail prices decreased compared to August. The average used-vehicle listing price decreased to $25,393, down from the revised $25,517 at the beginning of August but up 1% compared to the levels observed a year earlier.

AVERAGE USED-VEHICLE LISTING PRICE

Price-conscious buyers have limited options for affordable used vehicles. Used cars priced below $15,000 continue to have low availability, with only 29 days’ supply, which is the lowest it has been since March, and 14 days below the overall industry average. The top five sellers of the month were listed at an average price of $23,571, more than 7% below the average listing price for all vehicles sold. Once again, Ford, Chevrolet, Toyota, Honda and Nissan were the top-selling brands, accounting for 50% of all used vehicles sold.
