The used Class 8 truck market showed mixed results in September, with same-dealer sales inching closer to the six-month volume average, according to a recent ACT Research report.

Volumes gained 8% from August but are only up 1% year-over-year. The average age of Class 8 used trucks climbed to 93 months, while average prices slipped by 4% month-to-month and 8% compared with the same month last year.

While truck sales are strong overall, the usual summertime slowdown seems to still be affecting volumes.

“According to our dealer conversations, used truck sales continue to be strong overall, but some dealers have reported a slowdown in used truck sales, with the summertime lull hanging on a little longer than usual,” said Steve Tam, ACT vice president-commercial vehicle sector. “One factor affecting used truck sales is that the new truck model year is looming, meaning trucks are close to celebrating their model year birthday.”
