Well, the convergence of cars and trucks depreciating at the same rate lasted all of a week.

The newest Black Book Market Insights report showed truck segments deprecating only by 0.9 percent last week, much less that in comparison with the car segments, which depreciated by 0.31 percent overall.

In fact, editors noticed three specific truck segments increased their value, including the full-size van, small pickup and full-size pickup.

Black Book also mentioned the recent truck performance produced a better than the average decrease since the firm spotted depreciation of 0.17 percent per week during the previous four weeks.

While those three truck segments saw an uptick, sub-compact luxury crossover/SUV and compact luxury crossover/SUV values dropped the most by 0.37 percent and 0.27 percent, respectively.

Over on the car side, looking at volume-weighted data, editors reiterated that overall car segment values declined by 0.31 percent last week. In comparison, the market values had decreased on average by 0.35 percent per week in the previous four weeks.

Within car segments, Black Book noted sub-compact car and compact car segments performed the worst, decreasing by 0.52 percent and 0.85 percent, respectively.

“Higher depreciation continued in sub-compact car and compact car segments driven by recent drop in gasoline prices. The average U.S. gas price per gallon has dropped by over 10 cents in the last three weeks,” said Anil Goyal, Black Book’s senior vice president of automotive valuation and analytics.

When Black Book’s representatives in the lanes reported back to headquarters, the dealer chatter continued to focus on trucks. And it came from both ends of the country.

First in North Carolina, “Had a lot of comments about high prices from dealers trying to buy nice, low mileage trucks.”

Then in Washington, “Pickup trucks are still king here. Mid-size and compact sedans struggled more than the past few weeks.”

The other anecdotes gave an indication of where dealers stand as the Fourth of July passed.

From Texas: “Dealers say they are building inventory around the July 4th holiday.”

In Colorado: “The dealers say they need inventory and are searching all of the resources to find their type of vehicles.”

And finally in Pennsylvania: “Most of the sales resulted from online buyers, as there weren’t many people in the lanes.”
