Used Cl8 Retail Summary Heat Map October 2025 PrelimClass 8 used truck sales were up nearly 10% in October, buoyed by a huge volume spike in the auction market, ACT Research reported Friday.

“Auction sales, uncharacteristically strong in October, bucked their typical first month of the quarter drop to expand by 19% month over month. Wholesale transactions expanded, gaining 10% month over month,” says Steve Tam, vice president at ACT Research. 

The market wasn’t quite as strong in the retail space, up just 0.3%. Tam says historically that number would have been a bit higher. Overall, the company market was up 9.5% in October.

“The [retail] market fell short of historical seasonality, which called for a 2.8% month-over-month increase,” Tam says.

Tam notes retail price stumbled a bit too, with the preliminary average retail price (same dealer sales) of used Class 8 trucks softening for the third consecutive month, shedding 3.5% month over month to $54,160. 

“October’s decay was contrary to seasonal expectations, which called for a 1.8% bump,” Tam says.
