As the spring market comes to a close early this year at auction, NADA Used Car Guide expects wholesale prices to continue to fall over the course of the current week.

NADA UCG expects an overall slight decline of 0.2 percent, or $25, relative to the two-week average.

Some of the biggest percentage declines are expected in the midsize car segment, predicted to decline by 0.4 percent, or $40.

The luxury utility segment is also expected to drop in price by 0.3 percent, or $75, followed by the large SUV segment falling 0.2 percent, of $50.

NADA UCG reported that compact utilities and midsize utilities will see minor declines, as well, each dropping by an average of less than 0.2 percent, or $25.

The compact car and luxury car segments are expected to remain flat relative to their respective two-week averages.

Meanwhile, only two segments are expected to see mild growth this week. Midsize vans are anticipated to increase by 0.8 percent ($125), followed by large pickups at 0.2 percent ($50).

This prediction is similar to action in the lanes cited last week by Black Book's Ricky Beggs.

Last week, the truck segments Black Book tracks saw considerable activity, as Beggs contributes much of the recent price increases within these segments to “functionality.”

Beggs said, “We feel functionality is the driver behind the interest and retention levels of these type vehicles (trucks). Several of these segments are mirroring similar sales trends as new models.”

Out of all the price adjustment Black Book editors made this past week, 54 percent were increases.

Interestingly, Beggs explained that the volume of increasing adjustments within the truck segments and models was over four times the level of the cars.

Four- and two-week AuctionNet wholesale average prices are created by collecting all AuctionNet records for vehicles  up to five years of age for a specified period of time.  Prices are then adjusted for changes in mileage and mix.

Current week prices are based on NADA's proprietary used-vehicle value model which includes assumptions for new-vehicle prices, used-vehicle supply, gasoline prices, and other economic factors.
