GM Extended Warranty Information
If you are purchasing an GM, or if you already own one, you may be thinking about getting some level of coverage beyond the normal manufacturer's warranty. Although GM's are generally very reliable vehicles, an extended auto warranty may provide you with protection to offer you the peace of mind you are looking for. GM Coverage programs can either extend the original level of coverage that came with your vehicle, or offer you a limited extended warranty plan. These plans are accepted nationwide at all GM dealers, and also afford you with most of the benefits usually granted with new car purchases.

GM Extended Warranties - Independent Companies
Although GM offers a very good extended warranty, many consumers feel more comfortable joining a third party provider. With a third party plan there are no restrictions regarding where you need to bring your vehicle, allowing you to go to any garage or mechanic in the country. This advantage will free you of the hassles of having to always deal with a dealer, make an appointment days away, and wait all afternoon for your repairs to be finished. You should investigate your options before picking your extended warranty plan.
