What Does Certified Pre-Owned (CPO) Mean?

A Certified Pre-Owned or CPO, car is a type of used car. Most often late-model, they differ from run of the mill used cars by having been refurbished, and certified by the original dealer as being as good as new. They also typically include a extended warranty from the manufacturer. Luxury automobile marques Lexus and Mercedes-Benz were among the first to create CPO programs in the 1990's.
