I have had my Avalanche for 3 yrs. now. No problems to report, just oil changes and gas! Very roomy interior, love the leather. Drives great, gas mieage is good I think considering the truck and its capabilities. After all, gas mileage in an V-8 is really up to the driver! Overall, I am very happy with this truck and I would recommend it highly to anyone.
Driveablity and powertrain. Also like interior features and Bose sound. Mine has no plastic on body sides. I think it enhances the look on truck.
