What does Certified Pre-Owned (CPO) mean?
There is no industry standard for CPO programs. Every CPO program is different. Buyer beware!
There is no industry standard for certifying a used vehicle, there is no industry standard for the inspection process, there is no industry standard on who performs a CPO inspection, and there is no industry standard on the type of warranty or the duration of the warranty.
A CPO program is basically some type inspection and warranty. Be sure you understand the CPO inspection is not the same as a pre-purchase inspection and what the warranty covers before you purchase.
Most CPO warranties cover only the drivetrain (engine and transmission). 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 nearly all repairs. In most cases, a used car buyer can purchase the same warranty coverage for less than the extra money spent for a Certified used vehicle.
