As wholesale prices begin to come down, pre-owned retail prices ticked up this month after remaining relatively consistent for most of the first quarter. But some of the pricier units bucked the trend, making up nine out of the top 10 vehicles that saw the biggest price drops in April.

According to a recent post on the Cars.com “Kicking Tires” blog written by Mike Hanley, luxury-car prices fell again this month, while mainstream models continued to see price hikes. The company notes that its lists include 2011 to 2013 model-year vehicles, and each eligible model must have at least 250 in the Cars.com national inventory.

The only mainstream brand unit to make the list of decliners was Hyundai’s full-size Equus sedan at No. 10, which is incedentially still considered a luxury vehicle.

Luxury models have made up the majority of cars in the top 10 every month so far this year, the Cars.com report noted.

Overall, used retail prices have risen by a slight 0.75 percent (or $175) this month to reach an average of $23,418, according to the site.

“The increase might be a reflection of more shopping activity as the spring selling season begins following a long, cold winter in many parts of the country,” Hanley wrote in the report.

Topping the list this month for biggest used-car price drops was the Land Rover Range Rover SUV, which saw prices fall by 4 percent (or $2,871).

Next up was the Audi A3, which fell by 3.1 percent (or $752), and the Mercedes-Benz CLS-Class, which saw a 2.9-percent (or $1,730) drop.

As for the models that saw the biggest price jumps, the results were much more varied.

The Chevrolet Express 1500 full-size van had the largest price hike with a 2.9-percent ($594) increase.

The GMC Sierra 3500 and Nissan Leaf, which were up 2.6 percent ($1,158) and 2.5 percent ($488), respectively, followed closely behind.

Black Book Analysis on Wholesale Trending

On the wholesale side of the market, this past week was an interesting divide between car and truck segments, which were moving in opposite directions. Overall, the market seems to be approaching some stability.

In a bit of analysis provided exclusively to Auto Remarketing on Monday, Black Book editorial director Ricky Beggs said that the market has apparently met the pent-up demand for the spring season, which should lead to some moderation in pricing.

For instance, Black Book had been seeing an average of more than 2,000 daily vehicle price adjustments, but that was trimmed to roughly 1,350 per day last week.

Breaking down the week’s changes in more detail, the truck segments, overall, were up $73, with 13 of the 14 categories showing positive movement. The luxury SUV class was the only one to decrease.

As for cars, their overall change was a downward movement of $13, which Beggs said marked the first time in five weeks cars have shown an overall negative change.

In his weekly video report on the used-car market, Beggs talked with the leadership of the International Automobile Remarketers Alliance. More on that interview can be found here. Black Book also announced a partnership with Cars.com on Monday. To learn more details, read Auto Remarketing's story on the deal.
