Though this trend has probably been on your radar for a while now, this statistic really drives the point home. In September, some truck segments showed a smaller year-to-date depreciation rate than the hit cars took in just a month.

Black Book offered this comparison in its breakdown of September price movement for model years 2010 through 2014. The compact car segment, which experienced the biggest depreciation rate in September, saw prices fall by 3.7 percent to an average of $8,923, while compact pickup prices have only dropped by 2.9 percent for the whole year.

These car and truck trends are continuing into October, as the latest Black Book Market Insights report shared car prices dropped by 0.76 percent last week, which is much higher than the average weekly depreciation of 0.47 percent seen over the previous 12 weeks. Trucks, on the other hand, saw prices drop by just 0.40.

Looking at overall average price movement for September, according to Black Book data, the average price of a used vehicle for model years 2010-2014 fell by 1.5 percent this past month, which stayed pretty consistent with August’s decline of 1.6 percent.

“Overall vehicle depreciation continues to hold up well, especially as we near the part of the year where heavier price drops are typically expected,” said Anil Goyal, vice president of automotive valuation and analytics for Black Book. “It’s very telling of the disparity between cars and trucks to see that we have some truck segments showing lower annual depreciation than what cars are seeing on a monthly level.”

The car segments saw average depreciation of 2.3 percent, while truck prices dropped by only 1 percent in September.

Compact cars led all segments with the highest depreciation for the month overall, while the full-size SUVs and full-size passenger vans held prices up the strongest in September. It is also important to note compact cars have seen prices drop by 16.9 percent year-over-year through September.

Full-size SUVs and full-size passenger vans each saw a 0.5-percent drop in price. Full-size SUVs ended the month with an average price of $26,512, which is a 3.7-percent drop from year-ago levels.

And among the car segments, the best performing units were the premium sporty cars, showing a 1.2-percent drop from August. This segment finished the month with an average price of $42,253, down 14.2 percent year-over-year.
