Certified pre-owned vehicle sales at Mercedes-Benz Canada reached their highest-ever quarterly share of the company’s overall used-car sales, the automaker said Thursday.

The company’s pre-owned division moved 3,492 used cars in the first quarter, a 9.2% year-over-year decrease.

Mercedes said 3,240 were CPO vehicles, which translates to a 92.8% penetration rate, an all-time high. It’s also a 6.0-percentage-point increase from a year ago.

Next up, Nissan had 983 certified sales in Canada last month, which marked a 40% month-over-month increase and a 12% year-over-year decline, said Joel Gregory, who heads up the automaker’s CPO program in Canada.

Meantime, Infiniti had its strongest month since October, with 148 CPO sales, Gregory said. This was a 43% improvement from February and a 10% year-over-year decline.

Over at Hyundai Auto Canada Corp., it was the second-best CPO March in history, with 1,127 units sold, said Charles Plewes, who is manager of CPO and remarketing national sales.
