Bought my Avalanche with 12K miles in 2003, it now has 167K and going strong. Considering the miles, other than routine things like, brakes, shocks, oil and tires, this truck has broken down very little. I had some front end work done, pitman arm and ball joints at about 100k, and a knock sensor at 150K. I replace the water pump at 150K because the gasket was leaking and I had to remove it to do the gasket. The original brakes lasted 100k. Still on the original alternator, radiator, exhaust etc.
The side panels and overall look of the truck. Very comfortable ride for trips to the cabin, even drove to Aspen CO from Minnesota. It tows, hauls and gives a nice ride.
The drivers seat is junk, kills my back after two or three hours.
