AOL Auto correspondent Bengt Halvorson offered a bit of caution before delving into some of the advantages CPO units can bring to consumers.

"Experts agree that while these automaker-supported programs might look quite similar, they vary greatly in how they're run at the dealership level," Halverson wrote.

"For some CPO programs it's a mere check to make sure nothing's worn out and in need of replacement, but for others the inspection is meticulous and could truly be called a factory-caliber reconditioning, with cosmetic blemishes touched up, worn trim pieces replaced, service conducted, and any other wearables like belts and brake pads preemptively replaced," he continued.

Halvorson went on to say that CPO units can "allow you to get a vehicle that's just like what you'd find in the new lot for a fraction of the price. Sometimes it adds the security of new-car ownership to an affordable used-car purchase. Other times it lets you purchase the best example of a sought-after used model that's no longer made, with the assurance of a factory warranty."
