Low gas prices and lots of winter weather compounded to bring strength to SUV prices at auction last month.

According to the latest data from Black Book, the average price of a used vehicle for model years 2009-2013 dropped by an average of 1.2 percent in February, which showed no change from January depreciation.

SUVs and trucks bucked trends with much lower-than-average depreciation last month.

The compact SUV segment led the month with the strongest retention rate, according to Black Book, with prices rising by 0.9 percent in February.

This was the only segment that finished the month off with a price increase, one that includes the Jeep Wrangler and Nissan Xterra. Vehicles in this segment finished the month off with an average price of $19,398, representing a 2.9-percent drop from year-ago prices.

Trucks touted seven of the eight best-performing segments, Black book personnel also pointed out.

“Perhaps the colder weather patterns helped heat up the sport utility vehicle and truck segments during February, as we saw great strength in SUVs and crossovers,” said Ricky Beggs, editorial director at Black Book. “Furthermore, while overall depreciation finished at -1.2 percent on the month, there are segments we feel could turn more positive due to spring type activity and continuing economic improvement. Also, some of the typical tax season cars might have reached their peak earlier in the calendar than last normal seasonal patterns.”

The only car segment hanging with the trucks in terms of retention was the upper midsize cars. This segment saw prices drop by only 0.3 percent, the third-best overall retention rate for February. Vehicles in this segment finished the month off with an average price of $10,924.

On the other hand, prestige luxury cars saw the largest depreciation during January, with a price drop of 2.8 percent.

Vehicles in this segment, which include the Audi A8 and Lexus GS, finished the month off with an average price of $34,714.
