How Does Mercedes-Benz Certified Pre-Owned Work?
To be certified under its CPO program, Mercedes requires its cars to be less than six years old and have fewer than 75,000 miles.  Like most CPO programs, eligible Mercedes CPO cars come from trade-ins, end-of-term leases, auctions, service loaners, and Mercedes company cars.  Prospective CPO cars must be accident-free, show a documented maintenance record, and have a clean history.
