CARY, N.C. -

Aside from surging numbers from 2016 model-year vehicles, auction sales volumes slowed in June, according to the latest Guidelines report from NADA Used Car Guide.

But year-to-date volume is still on the rise, particularly for late-model vehicles.

NADA Used Car Guide data indicates that there have been 2.29 million auction sales of vehicles up to 8 years old through six months of 2016. That beats year-ago figures by 5 percent.

There have been 1.34 million late-model vehicles (3 years old or younger) sold at auction this year, which is up 9 percent year-over-year.

Put differently, late-model vehicles represented more than 58 percent of auction sales volume in the first half. 

One slice of the late-model segment — 2016 vehicles — were particularly strong in June.

This was the only segment to see an increase in auction sales volumes (up 30 percent) for the four weeks ending June 27, NADA Used Car Guide said.

However, overall auction sales volume was down 6 percent.

Year-to-date, the 2013 model-year class has seen the greatest increase (27 percent) with 509,000 cars being sold at auction. This is no surprise, NADA Used Car Guide said, with off-lease gains as high as they are.

Segment-wise, large pickups were the biggest story in the first half of the year. Their auction sales volume climbed 34 percent, more than any other segment, NADA Used Car Guide said.
