Bought our 06 Envoy SLE brand new late 2006. It now has 338,000kms. This SUV has been amazingly dependable through the years. Never had any major issues with the engine or transmission, both still operate very well and smoothly. Most expensive repair was a fuel pump at 240,000 km other that that nothing major ever went wrong. Still one of the best riding SUV's I've ever been in or driven, very quiet too. A few gripes include the average fuel economy and some overly cheap interior bits that had a habit of working loose. Overall have been very pleased with this model. We are replacing it with a new Yukon and hope to have the same service that the Envoy provided.
