Certified pre-owned programs often provide shoppers with a higher-value alternative to new cars, with a warranty that's nearly as good. Now GM is making some changes to its program in order to make it even more attractive.

The program once known as the GM Certified Used Vehicles Program will be renamed Chevrolet/Buick/GMC Certified Pre-Owned Vehicles.

Also, owners will get standard maintenance--including oil changes, as measured by the vehicle's oil life monitor--taken care of for two years or 30,000 miles. Tire rotations and multi-point inspections are also included.

The program will continue to offer a 12-month/12,000-mile bumper-to-bumper warranty and a five-year/100,000-mile limited powertrain warranty with 24-hour roadside assistance and courtesy transportation. The initial inspection now moves from 117 points to 172, and satellite radio and OnStar trials remain part of the program.

Cadillac's Certified Pre-Owned Vehicle program will be unchanged.
