Price softening in the lanes has become a weekly trend as we head into summer.

For the third week in a row, NADA Used Car Guide is predicting prices will drop by 0.3 percent (or $50).

Midsize vans are expected to see the only increase in price this week, rising by 0.3 percent ($50).

The van segments experienced strong price retention last month, as well.

Full-size passenger vans led all segments with the strongest monthly retention, with rates growing by 2.5 percent in May, according to Black Book data. This segment was followed by full-size cargo vans, with a lift of 1.7 percent.

An improving economy and high construction rates are pushing strong retention in the van segments.

"There continues to be healthy demand for cargo vans because of the construction activity and the improving economy. We anticipate this will continue into the near future. Passenger vans are holding their retention right now because this is a category that is in sync as far as supply and demand," Black Book editorial director Ricky Beggs told Auto Remarketing.

Coming back to this week’s trends, NADA UCG predicts luxury utilities are expected to see prices remain flat this week, with all other segments set up for price declines.

Losses will be led by the compact utitlity segment with average expected declines of 1 percent, followed by compact cars (down 0.7 percent) and luxury cars (0.6 percent).

“Smaller declines are expected in all other segments as prices are expected to slip by 0.1 percent to 0.4 percent,” said David Paris, automotive analyst at NADA UCG.

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.
