The large pickup and large utility segments continued to show strength, with prices for each segment falling 0.5% and 0.3%, respectively, compared to the prior month.

Sales volume at auction was also on the decline during July. However, the firm noted, the decline is typical for the time of year. July’s decline marked the fourth monthyl decline in a row. On a year-to-date basis, however, volume is up 6%.

Looking forward, depreciation is expected to accelerate as the market enters what is typically the softest part of the year, according to the NADA.

August’s used-vehicle prices are expected to fall by 2.5% to 3% compared to July’s figures. Subcompact car prices are expected to drop by about 3% on a monthly basis, while compact, mid-size and large car prices are expected to fall 2.7%.

Compact utility and mid-size utility prices are expected to decline 2.3%, while mid-size van prices are expected to fall 2.7%. Large pickup and utility pricing are expected to suffer the softest decline at 1.8%, while luxury segment losses are expected to average about 2.5%, according to the firm. In September and October, prices are expected to fall around 3.2% to 3.7% per month.
