What is a certified pre-owned (CPO) vehicle? A certified pre-owned vehicle is a used car, SUV, truck, or van that has been inspected, refurbished, and certified by an accredited professional. A CPO vehicle often includes an extended warranty, special financing, or other additional benefits. Manufacturers list their own individual requirements to obtain a CPO credential.
