Perhaps used vehicles aren’t rolling over the curb at a pace some dealers would like, but you couldn’t tell by the wholesale-price trends and auction-activity observations Black Book shared on Tuesday.

The latest Black Book Market Insights report indicated that cars have continued their strong spring cadence of auction sales and activity. Editors determined the majority of smaller car segments, along with midsize cars, again saw price increases this past week, while just a few truck segments generated increases.

“The spring market surge continues for small and midsize cars while most truck segments see a decline,” said Anil Goyal, executive vice president of operations at Black Book.

Volume weighted, Black Book reported that overall car segment values increased by 0.24 percent last week. The reading nearly mimicked what editors spotted the past two weeks as market values had increased on average by 0.25 percent per week.

Within cars, the compact car, midsize car, and sporty car segments increased the most in value last week, rising by $47, $42 and $47, respectively.

Again volume weighted, Black Book found that overall truck segment values — including pickups, SUVs, and vans — decreased by 0.12 percent last week. In comparison, the market values had decreased on average by 0.20 percent per week during the previous four weeks.

Among the trucks, the subcompact crossover and compact van segments registered the most increase in value last week, climbing by $28 and $38, respectively.

Turning next to what Black Book’s lane watchers reported back to headquarters, perhaps what percolated out of Colorado summarized the spring market best.

“The spring surge remains here as we are in a seller’s market. If you are buying vehicles, be prepared to pay the price for inventory,” the representative in Colorado said.

And the recap out of Massachusetts relayed a similar scenario.

“Retail is still not great here, but you wouldn’t know it by what the buyers are paying in the lanes. Prices are still strong across the board,” Black Book’s representative stationed in that commonwealth said.

Black Book’s three other anecdotes all surfaced out of the Midwest, with activities that might be common nowadays in other parts of the country, too.

From Michigan: “Anything in good, clean condition with below average mileage brings strong money. Sports cars are beginning to show up and are strong also.”

From Indiana: “The nicer units along with pickup trucks remain scarce at the auction. Prices are high, especially on the older units, due to tax season.”

From Wisconsin: “Very active bidding and selling. Late-model off-lease units are selling very well.”
