Considering the same relative softness on the retail side of the market, the current movement in the wholesale arena doesn’t come as a “major surprise” to Black Book’s Ricky Beggs, who spotted overall price declines on both the car and truck sides of the market for the third straight week.

He said in the latest “Beggs on the Used Car Market” video report that the overall change in the wholesale market was a downward movement of $66, which is quite similar to the $68 decline spotted three weeks ago.

Only one of the 24 segments that Black Book tracks showed a week-over-week value increase.

“The adjustments this week reflected a trend similar to the past three weeks,” said Beggs, who is Black Book’s managing editor.

“As the recent few weeks of the market have been making some softening adjustments the overall percent of adjustments being increased was the smallest number since back in the winter and the week ending February 18, 2011,” he added. “With quite a few dealers telling us retail has recently been a little slower, thus the direction of the market is not a major surprise.”

Breaking it down by segment, the week-over-week drop-off in the truck segments slowed to $30, the lowest it has been in the last three weeks, according to Beggs.

The only one of the 14 truck classes  to see an increase — and the sole upward mover of the 24 car and truck segments — was the compact pickup truck segment, which was up $5. Luxury SUVs had the largest decline (down $83) followed by the full-size crossover (down $65) and the midsize SUV (down $54).

Interestingly enough, though its value fell $10, the full-size pickup class had its strongest week-over-week value retention in nine weeks.

Beggs questioned whether this dip has something to do with the gas-price alleviation that has occurred in recent weeks.

“Is this trending a reaction to the declining gas prices at the pump? If you think so, then why didn’t the luxury SUVs do any better than the previous 12 weeks?” he said.

Moving over to cars, these segments were slightly different than the trucks: instead of the value decline slowing down, the drop-off was actually the steepest it has been in recent times.

Moreover, all 10 segments decreased.

“Taking a closer look at the car segments, the 10 segment types decreased the largest amount during the recent downward adjustment in the market at $22,” Beggs pointed out. “The last time all the car segment types trended the same direction was the week ending May 6 when all 10 car segments increased with an overall week-over- week change of $49.”

Showing the largest dip was the prestige luxury car segment (down $89). At a distant second was the luxury level car segment (down $23), followed by the entry level car segment (down $21).

Beggs, however, did point out some rather modest decliners like the entry sporty car class (down $3) and the sub-compact car segment (down $8).
