Hello all. I have the opportunity to purchase a wrecked '11 Avalanche and repair it. It was hit in the front end and will need minor repairs like a new fender, hood, grill, bumper, headlight and driver air bag. Shows 117k on the dash. Seemed to run pretty good. It is the Z71 model. I was curious if y'all knew of any known/common issues with these trucks. Anything that I need to look for? Thanks in advance!
