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 declined 24% month-over-month in August, counter to the typical seasonal increase, while the average retail sale price increased 2.2% to $64,367. Compared to August 2025, retail sales were up 12% year-over-year and prices rose 11%.

“The notable drop in used Class 8 sales this month is not necessarily a reflection of weaker demand, but more likely a result of tightening inventory,” said Steve Tam, Vice President at ACT Research. “Dealers across the country are reporting that used truck inventory is increasingly hard to come by, and our analysis of multiple advertising sources confirms that available units are down meaningfully from earlier in the year. With new truck sales also running below last year’s pace, fewer trades are making their way into the used market, supporting higher prices despite lower sales volumes.” 

ACT’s Used Classes 3-8 report provides data on the average selling price, miles, and age based on a sample of industry data. In addition, the report provides the average selling price for top-selling Class 8 models for each of the major truck OEMs – Freightliner (Daimler); Kenworth and Peterbilt (Paccar); International (Navistar); and Volvo and Mack (Volvo). This report is utilized by those throughout the industry, including commercial vehicle dealers, to gain a better understanding of the used truck market, especially as it relates to changes in near-term performance.
