AuctionNet wholesale auction sales reached 601,300 vehicles in May, up 3.5% from last May (selling day adjusted), according to monthly figures released June 12 from AuctionNet.
While up, May’s volume performance was far more muted than April’s strong 12.6% year-over-year rise. Monthly, sales fell 3.4% compared to April, which was the strongest month of sales since July 2020.
AuctionNet sales reached 3.05 million vehicles during the first five months of the year, up 7.1% versus 2024 (selling day adjusted). Year-to-date, sales are down 14% compared to the same period in 2019.
Dealer Auction Sales
Rising nearly 17% on a prior-year basis, dealer auction sales were buoyed by an influx of trade-ins in April stemming from consumer pre-buy activity in anticipation of higher prices due to tariffs.
Given April’s pronounced growth, May was likely to experience some correction in dealer volume. That’s exactly what occurred. Dealer sales grew by a lesser 4.6% last month compared to May 2024, and they were down more than 7% compared to April (selling day adjusted).
Commercial Auction Sales
Commercial sales growth also slowed last month from April’s 10.5% increase, with growth moderating to 4.5% on a prior-year basis and slipping 0.3% from April.
Off Rentals Up, Off Leases Down, Repos Up
- Overall, sales of 1-to-2-year-old vehicles, which include a heavy mix of off-rental units, continued to grow appreciably last month, rising nearly 23% compared to last May and 19% versus April.
- Sales of three-year-old vehicles, which include many off-lease units, fell 19% on a prior-year basis and 7% versus April.
- Four- and five-year-old vehicle sales dropped 13.4% on a prior-year basis, while sales of vehicles 7-plus-years-old grew 8% year-over-year. Note that commercial sales for the latter group rose 14% year-over-year in May, reflecting continued repossession volume growth.

Tesla dominated auction sales of used electric vehicles in May. Total EV sales were up 48% compared to May 2025.

EVs Show Highest Percentage Sales

Wholesale Used Vehicle Prices Flatter
Wholesale prices rose 2% in April compared to March but gave up the same ground in May as prices dropped 2% versus April. While down, the fall was slightly better than the 2.7% month-over-month decrease recorded in May 2024.
Prices in May were 5.6% stronger than in May 2024.
