GAINESVILLE, Ga. -

Are gas prices finally on the way down? According to the latest “Beggs on the Used Car Market” report, gas prices at the pump made the biggest week-over-week change since July, and wholesale price changes may be directly impacted.

Ricky Beggs, managing editor of Black Book, said gas prices fell by $0.13 this past week – the biggest change in fuel rates since the $0.14 increase after the final week in July.

And he asks, “Is there a direct correlation of gas prices to the market value changes?”

There may be, as car prices in the lanes seem to be declining at a quick pace, while many of the truck segments remain more consistant.

In fact, car segments, overall, are beginning to change at a faster rate as the weeks go by: the average segment change for cars saw a slightly larger decline last week, falling $68; the week before, there was a $67 decline.

On the other hand, the truck segment change improved to  a drop of just $53; $5 better than the $58 downward adjustment the prior week, according to Black Book.

But even though gas prices are on the way down, Beggs contends, “These results are contrary to common sense when fuel economy is considered. A year ago with gas at $3.46 a gallon, $0.22 less than this year, the cars average segment change was at (negative) $75; $7 worse than this year, while the trucks were $10 better a year ago.”

That said, truck prices are seeming to remain more consistent in the lanes, as some car segments see large declines.

“I was looking for cars, trucks or segments that were taking a consistent trending pattern over the past month or so. The full-size cars have had larger declines progressively for the past five weeks. It started at (negative) $25 for the week ending September 28 and finished this past week at  (negative) $70,” Beggs said.

That said, there are still some larger units seeing price drops, as well. The midsize crossovers dropped $17 for the week ending September 28. And then the depreciation amounts for the following three weeks were $61, $86 and $104, respectively, before finishing this past week at  down $131.

But Beggs stressed these big drops are not unusual for this time of year.

“With these trends, keep in mind we are deep into the fall of the year when the market should be adjusting downward,” he said.

On the other hand, there was one segment that has seen steadily improving adjustments over the past few weeks — another trend that is defying high gas prices.

The full-size SUV segment has had a more “positive” price pattern, according to Beggs.

This segment fell $74 during the week ending Oct. 5, and the price changes have moved in a positive direction each week since then (the declines slowed to $58, then $51 and this past week at $4).
