LAWRENCEVILLE, Ga. -

In comparing the depreciation patterns of car segments versus those of truck segments, Black Book has noticed a “large disparity” bubbling to the surface.

And this gap might be most notable when taking a gander at the list of month-over-month used-vehicle pricing changes for the 25 individual vehicle segments that Black Book tracks.

The three segments with the biggest sequential used price drops in June were all smaller car types, Black Book pointed out: the entry-level cars (down 4.7 percent), compact cars (3.9 percent) and entry midsize cars (down 3.5 percent).

In fact, the eight biggest declines for the month were all car segments. 

Conversely, the seven segments showing the most retention/least depreciation were all trucks, led by the compact SUVs, whose prices climbed 0.8 percent. That segment was the only one (car or truck) to show a month-over-month increase.

Midsize pickups were essentially static from May, while compact pickups and full-size passenger vans dipped 0.2 percent each, full-size cargo vans were off 0.3 percent and full-size CUVs were down 0.5 percent, as were subcompact CUVs (a relatively new vehicle category whose strength Black Book examined closely this spring).

Another sign of this gap is the trending over the past three months. Overall car segments have seen a 4.7-percent price drop. Trucks have been fairly static, down just 0.6 percent.

“The disparity between car and truck depreciation has definitely shown itself over the last few months, driven largely by the hot demand for trucks throughout 2015,” said Anil Goyal, vice president of automotive valuation and analytics for Black Book.

In June, car prices fell 2.5 percent month-over-month and trucks fell 0.9 percent. The 12-month change for cars has been a 16.5-percent downturn, with trucks falling 10 percent.
