Chevrolet Avalanche 1500 Reviews
I am a pilot car for the oversize loads and travel all over the country. I currently have 360,000 miles on my Avalanche and it is still in great shape. I have had trouble with the instrument cluster (speedometer not working). Have also had trouble with the heating/cooling functions. Other than that, it has held up well.
I absolutely love my 02, Brakes are a slight downer but I absolutely love this vehicle. The plastic cladding is a lifesaver in campus parking lots, and when they fade just slap a coat of Refinish Restore on it and its good to go. I put a Cold Air Intake in it and a cat back exhaust and it howls, sadly im pushing 120,000 miles, but I might turn it into a million mile chevy just because I cannot bear to part with it
