what is certified used car
From Wikipedia, the free encyclopedia. A certified pre-owned car or CPO is a type of used car. Most often late-model, they differ from other used cars by having been inspected, refurbished, and certified by a manufacturer or other certifying authority.They also typically include an extended warranty, special financing, and additional benefits.actory CPO cars are generally five years old or newer and have less than 80,000 miles. They often cost more than vehicles certified by independent authorities, and are higher priced than a non-certified used vehicle. Independent programs can represent good value and an alternative to an OEM program.
