Though some segments will fall outside the overall trend, wholesale prices are expected to remain flat over the course of this week, despite expected seasonal softness.

That’s according to NADA’s AuctionNet data, which shows that losses this week will be led by the compact car segment.

This fuel efficient segment is expected to see prices fall by 1.8 percent, or $175.

This may be due in part to lessening demand and lowering gas prices.

According to Energy Information Administration, the average price of regular grade gasoline fell from $3.21 to rest at $3.12 last week.

And Black Book reported Tuesday as gas prices drop and demand softens, entry-level and small cars are expected to see noticeable price drops this month.

The entry midsize cars are predicted to lead with the biggest drop, falling by 7.5 percent from the third quarter and 13.7 percent year-over-year. The compact cars will most likely follow with a 6.3-percent drop from Q3, according to Black Book data.

This week, midsize car prices are expected to see the second largest price drop in the lanes, falling by 0.5 percent (or $50), according to NADA.

Large pickups and compact utility segments are expected to decline slightly, as well, with drops ranging from $25 to $50.

However, all other segments are expected to see slight price appreciation, said David Paris, automotive analyst at NADA, except for the luxury cars, which are expected to see prices remain consistent with last week.

Luxury utility vehicles are predicted to see the biggest price increases this week, rising by $100.

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.
