Chevrolet's Certified Pre-Owned program accepts six-year-old vehicles with fewer than 75,000 miles. Vehicle sales date determines eligibility. Certified pre-owned Chevrolets include a 6-year/100,000-mile powertrain warranty. A bumper-to-bumper limited warranty will protect these vehicles for one year/unlimited miles after the first manufacturer's warranty of 36 months or 36,000 miles expires. Before selling, Certified Pre-Owned Chevrolets must pass a 172-point examination. Towing and 24/7 roadside assistance is possible.
