Six-year-old and under cars with less than 75,000 miles are eligible for the Chevrolet Certified Pre-Owned program. The date of the original sale of the vehicle determines eligibility. Chevrolet offers a 6-year/100,000-mile powertrain warranty on its certified pre-owned cars. After the three-year/36,000-mile new-car warranty ends, these cars are additionally covered by a one-year/12,000-mile bumper-to-bumper limited warranty. All Chevrolet CPO cars must pass a rigorous 172-point examination before being sold as certified pre-owned. Towing and 24-hour roadside assistance may be provided as additional perks.
