CARY, N.C. -

Several brands have already reported all-time records for monthly certified pre-owned sales — and that may not be the last of it.

Starting things off with Chrysler Group, the company sold 13,760 certified vehicles in August, which was its best month ever for CPO sales.

Hyundai, which also posted its strongest certified sales month of all time, sold 9,254 CPO units in August for a 26.7-percent year-over-year hike.

Mazda sold 4,469 certified vehicles during August, marking a 22-percent increase. This was Mazda’s best-ever CPO sales total, says manager of CPO and remarketing Roger Basa, who indicated that “CPO Inventory levels are at historic all-time highs.”

Kia also had its best-ever month for CPO, selling 4,883 units in August. This marked a 36.83-percent increase. 

Over at BMW Group in the U.S., the company is reporting the best August ever for its BMW brand’s used-vehicle sales (which include CPO and non-CPO used) as well as an all-time high for the MINI’s used sales (again, CPO and non-CPO combined). Those totals: BMW at 19,318 units and MINI at 2,561.
