CPO (certified pre-owned) is most often a late-model used vehicle that has been inspected and certified by a manufacturer or other certifying company and typically includes an extended warranty.
However, there is no industry standard for what constitutes CPO certifications. There is also no industry standard for which items are inspected nor who is qualified to perform a CPO inspection. A CPO can be very different from dealer to dealer and from manufacturer to manufacturer.
Most CPO programs come with some type of warranty. Be sure you understand what is covered and for what length of time before you purchase. All warranties are not the same.
Many used car buyers believe that a CPO vehicle comes with a comprehensive bumper to bumper warranty, only to find out they are responsible for repairs after the sale.
You must determine if the extra amount you pay for a CPO vehicle is worth the cost.
