Used Class 8 truck same dealer sales volumes fell in July, posting an 8% month-over-month drop, following a double-digit month-over-month increase in June, according to the latest data from ACT Research.

Additionally, the report noted that sales were down year-over-year and year-to-date by a similar amount.

“Despite the volatility month to month, the overall trend is on an upward trek, with year-to-date volumes only 7% off last year’s numbers. Year-to-date declines over the last several months have been fairly consistent, possibly signaling a stabilization in volumes,” said Steve Tam, ACT’s vice president of the Commercial Vehicle Sector. “Dealers are reporting an increase in customer traffic, but this has not led to surging sales.”

The report from ACT 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.
