Used-vehicle sales have so far followed normal summer season slowdown patterns, bumping up inventories, though prices aren’t helping with demand.

Average used listing prices were flat month-over-month in June but were still up 6% from a year earlier, Cox Automotive reported.

Combined franchised and retail used supply ended the month at 2.1 million units, or 47 days’ supply, up 1% from May, as the average listing price of $27,027 likely contributed to softened retail sales. Used-vehicle prices were up in almost all age groups.

Deliveries were down about 2% from both May and a year earlier despite credit access reaching a nearly 11-year high.

Inventory was still fairly limited based on “recent historical norms,” Cox said.

In the certified preowned segment, sales were up 5% year-over-year to a little more than 210,000 units, though that’s down about 8% from May and represents about a half percentage point drop in the share of total used retail sales. CPO deliveries are down about 2% in the first half of the year from 2025’s first half.
