January 2015 retail sales data shows that the average selling price of a 3-year-old aerodynamic sleeper tractor this month was $87,476. This figure was higher than January 2014’s average by $2,619 (or 3.1%).

Each January, we update our definition of “3-year-old” to reflect the switchover to production of the new model year. As such, we are now considering 2013 model year trucks to be 3 years old. 

The model with the largest increase year-over-year was the Volvo VNL 630/670, with a $11,723 (or 14.0%) increase. Close behind was the Peterbilt 587, with a $9,032 (or 10.5%) increase. The International ProStar turned in a surprisingly strong result for that model, coming in $7,064 (or 11.1%) higher. Volvo’s 730/780 was the final model to increase year-over-year, coming in $6,568 (or 7.1%) higher. See graph below for details.

Keep in mind individual months’ results can sometimes be misleading due to low volume for a particular model and differences in mileage. We do adjust for mileage, but occasionally the difference between models is so great that our adjustment might not fully account for the impact on value. The Freightliner Cascadia is a good example of that factor this month, with its average mileage of 379,348 a whopping 153,746 (or 68.1%) higher than the 587’s. Given the Cascadia’s outstanding performance in 2014, we consider this month’s result an anomaly.

Going forward, we expect models to return to positioning similar to last year. The positive takeaway is that late-model sleepers are still bringing strong money, despite the higher supply.
