Black Book reported on Tuesday that wholesale prices for both cars and trucks have now increased for nine consecutive weeks, which includes the stretch when values often peak then level off going into summertime.

With overall prices climbing another 0.11% last week, Black Book also mentioned in its newest installment of Market Insights that the auction conversion rate stayed strong at 62%.

“The market continues to defy typical seasonal trends,” analysts said in the report while also noting that the first full week of May averaged an overall price drop of 0.20% before the pandemic.

“Nationwide sales rates remain robust, consistently averaging above 60%, with strong bidder attendance and level of bidding activity,” Black Book continued.

Black Book pointed out that its estimated used retail days to turn is now at roughly 37 days. And if dealers are turning their inventory that quickly, evidently there are plenty of potential units for replenishment in the lanes.

“Since the second week of April, total auction inventory has been rising across the country, reaching its highest level this year last week,” Black Book said. “Despite this increased inventory, conversion rates remained strong, holding at an elevated 62% last week.”

Those active buyers are having to continue to tap their floorplans deeper to get what they need to retail, and it doesn’t seem to matter if the vehicles are nearly new or long in the mechanical tooth.

Black Book said prices for cars less than 2 years old rose 0.18%, while values for cars between 8 and 16 years old ticked up 0.13%.

Among trucks, prices for units less than 2 years old rose by 0.18%, while values for trucks between 8 and 16 years old edged up by 0.11%.

A few other pricing trends called out by Black Book in the newest report included:

—After eight consecutive weeks of gains, averaging a weekly increase of 0.31%, prices for compact cars declined by 0.31%

—Values for full-size cars now have risen for 10 straight weeks courtesy of another increase of 0.45% last week.

—Prices for minivans jumped another 0.75% last week, following a 0.84% increase during the prior week. Over the past nine weeks, the segment has averaged a weekly value increase of 0.48%.

—After 11 consecutive weeks of value gains, prices for full-size crossovers/SUVs decreased 0.32% last week.

“As always, our team of analysts are focused on keeping their eyes on the market for developing trends and gathering insight,” Black Book said.
