The certified pre-owned market has now posted five straight years of record sales. According to industry sales figures released Wednesday afternoon by Autodata Corp., there were 2.55 million CPO sales in 2015.

Not only was this the best year ever for CPO, but it beat last year’s tally by more than 9 percent, Autodata said.

And more than a few handfuls of automakers reported record years, the company said: Acura, Audi, BMW, FCA Group, Ford Motor Co., Infiniti, Kia, Land Rover, Lexus, Maserati, Mercedes-Benz, Mini, Nissan, Porsche, Subaru and Toyota.

December itself was a solid month for CPO, as well.  Four programs — FCA, Infiniti Land Rover and Porsche — achieved all-time highs (December or otherwise) and the overall industry sold 226,967 certified vehicles for the month, which was the best December on record and a 13.1-percent year-over-year improvement.

That capped the best fourth quarter of all time, as the industry moved 624,624 CPO cars for a 4.8-percent hike.
