Higher-end models continue to see some of the biggest price declines in the lanes as we head toward cooler weather.

NADA predicts wholesale prices to drop by an average of 1 percent, or $150, this week, with the luxury models seeing some of the biggest declines.

For instance, luxury cars are expected to see a decline of around 1 percent this week.

Black Book’s Ricky Beggs also recently highlighted this trend in his latest video report, noting the real “softness” in the market for the cars and trucks is centered around the more expensive units, while the less expensive vehicles are holding their prices.

That said, large SUVs and compact cars are also expected to experience price drops equal to or above 1 percent this week, according to NADA data.

Consumer interest may be playing a role in the softness of compact car prices, as interest tends to wane when fuel prices drop.

According to Energy Information Administration data released this week, the average price of regular grade gasoline fell by five cents per gallon to rest at $3.41 last week.

Leading the expected declines this week is the midsize utility segment, which is expected to see prices drop by 1.3 percent or $225, according to NADA AuctionNet data.,

Also expected to see significant declines are the luxury utility and midsize car segments, which are expected to fall by 0.8 percent and 0.9 percent, respectively.

Losses for the remaining segments NADA tracks are expected to be less extreme.

Four- and two-week AuctionNet wholesale average prices are created by collecting all AuctionNet records for vehicles  up to 5 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.
