According to a preliminary report from Autodata Corp., full-year certified pre-owned sales figures for 2013 came to a total of 2.11 million units.

The best annual results in CPO history, this marked the first time the industry has ever sold 2 million or more certified vehicles in a year, Autodata said.

Fittingly, the year closed with the best December ever, as dealers posted 171,280 CPO sales. This was a 9.4-percent year-over-year increase, the firm’s report indicated.

Likewise, it was also the best fourth quarter ever for certified sales, with 525,693 units sold (up 16.3 percent year-over-year).

More than a dozen brands achieved best-ever years:   Audi, Ford/Lincoln/Mercury, Honda, Hyundai, Kia, Lexus, Mazda, Mercedes-Benz, Mini, Nissan, Porsche, Subaru, Toyota and Volkswagen.

December was a best-ever month for Porsche, Mercedes-Benz and Audi.
