While car values depreciated at twice the rate of truck values last week, this may seem like old news — but one new trend is now showing up on analysts' radar.

It’s not just the smaller cars feeling heavier depreciation as market correction from tax season highs, mid-size and larger cars are feeling downward pressure, as well.

According to the latest edition of Black Book Market Insights, overall prices for cars at auction dropped by 0.62 percent or $73 last week, which was higher than the average declines seen over the previous four weeks.

Trucks, on the other hand, saw values fall by just 0.27 percent or $44 last week, which is in line with movement seen over the past month.

“Depreciation rate on car segments picked up a little. While trucks continued to perform better, a couple of previously strong segments experienced a market correction,” said Anil Goyal, vice president of automotive valuation and analytics.

And for the car market, it seems lack of demand in the slower summer months might be contributing to lower prices and less movement in the lanes.

Black Book editors hear a buyer from Tennessee say, “Plenty of cars here today just not many buyers. Dealers say sales are soft on their lots at the present.”

Among the car segments, interestingly, segments across the board, not just the smaller units, experienced bigger drops in price last week than normal.

For example, the full-size cars saw prices drop by 0.91 percent or $90, the biggest decline out of all segments last week.

The upper mid-size cars also saw a large decline, with rates dropping by 0.77 percent or $86. The compact cars also saw larger-than-average drops, with rates falling by 0.87 percent or $72.

The story was a bit different for the better-performing sporty cars (-0.43 percent or -$69) and luxury cars (-0.21 percent or -$43).

Moving over to the truck side of the market, once again the full-size pickups experienced price strength last week, with prices dropping by a mere 0.09 percent or $17.

That said, two segments — compact pickups and full-size cargo vans experienced a market correction after several weeks of strong value retention, Black Book editors shared.

Compact pickup prices dropped by 1.01 percent or $151 last week, while the full-size cargo van segment experienced a decline of 1.01 percent or $71.

The best performing truck segment this past week was the minivan cargo units, which saw prices drop by just 0.01 percent or $1.

This slightly softer truck market was being noticed in the lanes, as well, as Black Book editors overheard a buyer from Michigan noting, “Trucks were actually a little soft here this week, probably due to low dealer attendance.”
