Both seasonality and increasing used supply are pushing wholesale prices down, according to Black Book’s Ricky Beggs.

This past week, the car segments experienced their largest average price decline since September, when they began 12 straight weeks of large price drops.

Beggs, editorial director and senior vice president of Black Book, poses the question: Could last week’s results be the start of a similar price drop trend for cars as seen last year?

Last week, car prices in the lanes fell by an average of $78.

The last time the car segments saw a bigger change was for the weeks ending Sept. 14 and Sept. 21 of last year, when they fell by $94 and $87, respectively, Beggs reported in his latest “Beggs on the Used Car Market” video report.

“There might be a trend appearing, as the year-ago car segment change was -$69. That year-ago change was the beginning of 12 consecutive weeks of greater-than-$60 declines week-over-week,” Beggs said.

While the cars continue to soften, the trucks overall average segment change improved slightly week-over-week.

The trucks saw an average  price decline of $41. And six of the 14 segments declined by less than $30, according to Black Book data.

The compact SUVs fell by only $3, leading the pack for retention strength.

On the other hand, the only truck segment to see a drop of at least 0.5 percent was the passenger minivans; the decline translated to a $45 price slide.

This segment has seen declines of 0.5 percent or more for each of the past six weeks.
