Truck depreciation is beginning to come in line with price drops for cars leading to a steady decline in auction prices.

According to the latest Black Book Market Insights report, truck depreciation has “picked up steam” over the last few weeks. This movement was highlights so far by last week’s drop of 0.41 percent or $65. This was the largest decline recorded by Black Book for truck segments so far this year.

The trend was backed up by buyers in the lanes, as Black Book editors overheard an auction goer from Nevada note, “Truck prices softened somewhat,” last week.

“Truck segment depreciation levels continue to increase but remain lower than those of car segments. Last week’s drop in values was the highest weekly decrease seen year-to-date for trucks,” said Anil Goyal, vice president of automotive valuation and analytics.

Last week, car values dropped by an average of 0.48 percent or $56, which is similar to depreciation levels seen over the past few months.

Black Book editors explained in looking at the 12-week segment moving averages, they can see how overall car depreciation averages “have reversed from the May-June time period in comparison to the July-August period,” with rates declining at a more rapid pace as summer progresses.

Taking a look at truck value movement last week, the best performers were the full-size passenger vans with depreciation of just 0.20 percent or $24. The minivan cargo segment also performed well, with a decline of 0.20 percent or $24.

Full-size crossovers took the biggest hit out of the truck segments with a drop of 1 percent or $164.

For the cars, compact cars continued to see significant price drops, declining by 0.72 percent or $58 last week.

The full-size car segment also saw prices suffer with rates dropping by 0.70 percent or $69.

On the other hand, Black Book editors pointed out, the luxury level car and prestige luxury car segments performed the best out of all the cars last week, with rates dropping less than 0.25 percent each.
