The certified pre-owned market was a popular topic during press conferences at the NADA Convention & Expo and in on-site interviews throughout the show.

The news that came out Monday afternoon further cements why: CPO sales have never been higher than they were last month.

According to Autodata Corp., there were 243,957 certified sales in March, which is an all-time high.

It’s also more than 11,000 units higher than the prior best-ever sum of 232,511, which was set in May. March CPO sales were also up 9.6 percent year-over-year and 15.4 percent from February, Autodata said.

The daily sales rate was 9,035 units, which was the highest ever, Autodata said.

On a brand level, setting best-ever CPO sales records were FCA, Ford Motor, Hyundai, Infiniti, Kia, Lexus, Nissan, Subaru and Toyota.
