The total supply of unsold used vehicles on dealer lots – franchised and independent – across the U.S. stood at 2.25 million units at the close of July. That was up from a revised 2.21 million at the end of June but down 9%, or 209,537 units, from the same time a year ago.

Total days’ supply at the end of July stood at 45, compared with 49 at the start of the month. The days’ supply was down 12% from year-ago levels. Days’ supply has been fluctuating in the mid-to-high 40s since April.

“Used-vehicle inventory has seen an improvement since March, but the overall inventory volume is still considered tight,” said Chris Frey, senior manager of Economic and Industry Insights at Cox Automotive. “Days’ supply, at 45, is on par with levels seen in 2019, but there has been a decline over the last several weeks, owing to increased used retail sales. Usually, we’d expect days’ supply to increase through year-end, but moderating prices and surprising summer demand may keep inventory numbers down.”

The Cox Automotive days’ supply is based on the daily sales rate for the most recent 30-day period, ending July 31, when sales were 1.49 million units, up 4.2% compared to July 2022. Total retail sales through the first seven months of the year are now up 6% compared to the same timeframe of last year.

The average used-vehicle listing price ended July lower than when the month opened and was down 4.1% compared to July 2022. The average used-vehicle listing price closed the month at $27,028, down 0.5% from the revised $27,167 at the end of June. Meanwhile, according to the Manheim Used Vehicle Value Index, wholesale prices saw a decline of 1.6% in July from June and were down 11.6% year over year.


Prices still falling, with fairly steady declines in the last two months.

As with new cars, and as has been the case for months, the lower the price segment, the tighter the inventory. Used vehicles priced under $10,000 had a days’ supply of 32, with days’ supply increasing with every higher price segment to the over $35,000 category with the highest days’ supply of 55.

Honda, Subaru and Toyota were the non-luxury brands with the lowest inventory of used vehicles in July. Honda had 38 days’ supply, while Subaru and Toyota both had 39 days’ supply. They were the only brands with sub-40 days’ supply. Most other mainstream brands – both luxury and non-luxury – had used-vehicle days’ supply under 60.
