While many consumers believe that purchasing a "certified" used vehicle means "good as new," leading consumer advocates say it's a rip-off, according to CBS 2, a news station affiliate in Chicago. Certified vehicles can cost much more, offering a used-car buyer peace of mind, but Rosemary Shahan of Consumers for Auto Reliability & Safety (CARS) told CBS 2 that certification doesn’t necessarily mean a whole lot. "There's no industry-wide regulation for certifying cars, and there's no government stnadard," she told the news station. Where franchise dealerships will offer certification backed by the automaker, many corner lots certify their own vehicles. Edmunds.com recommends asking to see the inspection report along with the car's history when buying certified pre-wowned vehicles.
