Used car price drops are expected to drop by over 1 percent at auction during this first week of summer.

NADA Used Car Guide’s AuctionNet data indicates used-car prices will drop by 1.1 percent or $175 this week.

Overall losses will be “moderate” said David Paris, automotive analyst at NADA UCG, but a few segments will buck the trend.

The mid-size cars are expected to see average declines of 1.6 percent, followed by compact cars, mid-size vans, compact utilities and large SUVs with losses all larger than 1.1 percent.

“The only segment expected to remain unchanged will be luxury utilities,” said Paris.

Smaller declines are expected in all other segments.

This over 1 percent predicted decline comes on the heels of a another week of softening in the lanes, according to Black Book data.

Last week, only only 28 percent of the price adjustment seen in the lanes were increases — the lowest rate since the week ending Feb. 21, according to Black Book.

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.
