I purchased my 2002 GMC Envoy 4 years ago with 43k miles on it. The only maintainance I have done is change the oil, brakes, and tires. Sometimes I will wash it. This has been the most reliable SUV I have ever owned. How do other people drive and maintain? Easy on the gas and this SUV will take care of you. I currently have 188,468 miles on it and still runs as smooth as butter. It is a 2002. 8 years later and still runs like new. Time to buy a new and pass this to my daughter.
