ATLANTA -

Hyundai and Lexus took top honors in the non-luxury and luxury categories, respectively, during Autotrader’s recent analysis of the best certified pre-owned vehicle programs.

While manufacturers tend to offer a range of perks with CPOs, Autotrader opted to focus on warranty coverage.

“The No. 1 benefit of any CPO program is the warranty, so we decided that the length of warranty should be the top criteria when choosing this year's Best CPO Programs," Brian Moody, executive editor at Autotrader, said in a news release. “Hyundai's CPO warranty is an extension of its exceptional new car warranty, and Lexus's warranty is simply the best in the luxury category.”

Hyundai’s CPO warranty offers five years or 60,000 miles of bumper-to-bumper limited coverage and 10 years or 100,000 miles of powertrain coverage from the car’s original sale date. The warranty offers a relatively low deductible of $50, and it is fully transferable to subsequent owners in a private sale.

Meanwhile, Lexus’s “L/Certified” program offers limited bumper-to-bumper coverage for up to six years and unlimited mileage from vehicle’s original sale date. There is no deductible for covered repairs, and the program offers complimentary maintenance covering the next four factory-recommended services for two years or 20,000 miles.

Honorable mentions in the non-luxury category were Chevrolet/GMC, Ford, Honda, Kia, Mazda, MINI, Mitsubishi, Subaru and Toyota. In the luxury category, they were Acura, Audi, BMW, Infiniti, Jaguar, Land Rover, Lincoln, Porsche and Volvo.

The selections for this year's Best CPO Programs were based primarily on warranty coverage, with a minimum of six years/100,000 miles for powertrain coverage. Other factors were bumper-to-bumper limited warranty length, warranty transferability and deductible amount.
