Billed as the best warranty of any full-lined automaker. The new coverage for all General Motors vehicles is now a fully transferable five-year limited, 100,000 mile powertrain warranty with no deductible. The new warranty will cover all 2007 model and beyond cars and light-duty trucks sold in the U.S. and Canada, and any 2007 model already sold will receive the new warranty retroactively. In addition, GM has expanded its roadside assistance and courtesy transportation programs to five years, as well. Please see dealer for details.
