Used Class 8 truck same-dealer sales volumes were down in July but still on an upward trend overall this year, according to an ACT Research report.

Sales volumes in July saw an 8% drop from June’s numbers, with year-over-year and year-to-date comparisons also seeing similar drops. However, last month saw a 15% increase in sales volumes, so July’s drop may not be as bad as it seems.

Dealers have been reporting an increase in customer traffic, but much like last month, this has failed to translate to a surge in actual sales.

“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,” said Steve Tam, ACT’s vice president-commercial vehicle sector. “Year-to-date declines over the last several months have been fairly consistent, possibly signaling a stabilization in volumes.”
