Interestingly, this past holiday week, wholesale price declines were expected to come to a halt.

According to NADA Used Car Guide predictions provided last week, wholesale price movement was expected to “stagnant” over the course of the current week as NADA expected overall prices to remain unchanged versus the two-week average.

And a few segments were even expected to see small levels of growth last week.

NADA UCG predicted the biggest percentage gains would be recorded in the compact car segments, with prices rising by 0.8 percent or $75.

Next up was the compact utilities, luxury cars, midsize cars, and midsize van, were all expected to inch up by about 0.2 percent or $25-50 apiece.

On the other hand, large SUVs were expected to drop the most last week, falling by 0.9 percent or $200, followed by large pickups with losses of around 0.8 percent or $150. This marks a shift in price trends, as these two segments have held strong price retention throughout most of 2013.

Two weeks ago, rate drops in these segments told a similar story.

Black Book’s Ricky Beggs is asking a question that many dealers may be pondering, as well: “What happened to the trucks?”

After holding strong price retention for most of this year, two weeks ago truck segments were showing a “significant market correction, with seven segments seeing a large downfall in values,” Beggs, senior vice president and editorial director of Black Book, said in his latest “Beggs on the Used Car Market” video report.

Lastly, last week midsize utilities and luxury utilities were each expected to decline by a combined average of 0.5 percent or roughly $100 apiece.

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.
