CPO (Certified Pre-Owned) means is that you can have peace of mind in purchasing this vehicle. Along with the tests that the dealer perform on each acquired pre-owned vehicle, the manufacturer has always stipulated additional tests and fixings. The vehicle is then flagged as ''Certified'' only after it has successfully passed all tests. You can buy this vehicle with confidence knowing that it has been certified accordingly. If you are shopping for a used car, then a Certified used car is the way to go.
