According to the latest State of the Industry: U.S. Classes 3-8 Used Trucks report by ACT Research, same dealer used Class 8 retail truck sales slipped 5.7% month-over-month in September, following a notable decline in August, while the average retail sale price decreased 1.9% to $64,007. Despite the near-term pullback, retail sales remained 6% higher year-over-year and average prices were up 12% from September 2025.
“The September decline in used Class 8 retail sales was directionally consistent with, but greater than, the typical seasonal drop,” said Steve Tam, Vice President at ACT Research. “While auction volumes rebounded in the last month of the quarter, retail and wholesale channels faced continued headwinds. Higher average miles and an uptick in vehicle age contributed to downward pressure on pricing, but the market’s longer-term trajectory remains positive, reflecting the resilience of carriers navigating a challenging operating environment.”

According to the latest release of ACT Research’s State of the Industry: U.S. Classes 3-8 Used Trucks Flash, preliminary same dealer retail sales of used Class 8 trucks declined for a second consecutive month in September, falling 7% month-over-month.
While auction sales surged 28% and wholesale transactions slipped 6% from August, total preliminary sales across all channels were up 6% sequentially, signaling that demand for used trucks remains fundamentally solid despite mixed results by channel.
The preliminary average retail price for same dealer sales of used Class 8 trucks softened more than seasonally expected, dipping 1.5% from August to $61,000. Pricing in both auction and wholesale markets also contracted, with the combined preliminary average sale price for all units dropping 7.1% month-over-month.
“While tighter inventories have been a persistent theme, it’s clear that higher interest rates and ongoing challenges in the driver pool and fuel costs are also influencing the used truck market,” said Steve Tam, Vice President at ACT Research. “Despite these headwinds, the sequential uptick in total sales and continued strength in freight activity suggest that underlying demand for used equipment remains resilient.”
