Car segment values were down last week, but rate of decline has moderated quite a bit from recent weeks.

According to the latest Black Book Market Insights Report, car segments were down an average of 0.19 percent last week (volume-weighted). However, the preceding eight weeks had an average decline of 0.34 percent, Black Book said in the report.

The only car segment to show any increase was the subcompact car, which was up only marginally (0.02 percent).

“Car segments show slower depreciation with subcompact car as the only segment experiencing a slight increase in values over the previous week,” Anil Goyal, Black Book's senior vice president of automotive valuation and analytics, said in comments accompanying the report.

One nugget that stands out: in the report, Black Book points out that the ninth week of 2015 started to show some signs of a “spring market.” At least in car values, that has yet to happen.

Trucks, meanwhile, were much more in line with recent weeks. Their values were down 0.35 percent, on average. The average change in the prior eight weeks was a dip of 0.31 percent, Black Book said.
