One of the best riding and driving vehicles I have ever owned. Awesome power and torque. Gas mileage is not bad for all the cubic inches you get. A good all around vehicle. I would definately buy another one.
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.
This is the first vehicle I have ever owned that it would truly hurt to give up. I bought it new 184000 miles ago and its been great, Outside of normal maintaince, I had the rear locking differential replaced at 140000 miles. The versatility of the midgate makes it so I can haul 4 x 8 drywall with 12' long 2 by 4's on top of them, sticking between the front seats, all out of the weather. Its great for hauling the grocerys, moving a kid to college or taking 5 full sized adults on a trip. Towing is ok, ride and comfort is better than any car or minivan that I ever owned.
I bought my truck new, I now have 316K miles on my truck and I still love it, you would never know this truck has so many miles on it, it still looks and runs like new,of course we've taken good care of it, from what I understand they don't make the Avalanche anymore and I guess I know why because they just keep driving on and on with no problems.
