Based on preliminary Class 8 same dealer used truck retail sales volumes (+10% m/m), it appears as though buyers are eager to take advantage of lower prices. Though, in total, the used truck industry contracted in October, according to the latest preliminary release of the State of the Industry: U.S. Classes 3–8 Used Trucks published by ACT Research.

ACT’s Used Class 8 Retail Summary

Compared to September 2023, average retail price and age were flat, with miles up 1%. Compared to October 2022, volumes increased 27%, but price, mile, and age saw declines.

According to Steve Tam, Vice President at ACT Research, “The gain in retail volumes stood in stark contrast to the other channels. Auctions were 62% lower m/m, while wholesale transactions fell 15% m/m.” He continued, “In total, the used truck industry contracted, with preliminary same dealer sales dropping 38% m/m.”

Tam concluded, “Historically, October is the best sales month of the year, averaging 9% above normal and 3.4% higher than September. However, shifting auction volumes are rapidly impacting overall seasonality.”
