I bought an 07 like that.... brake lines, fuel lines (all of them.... such a PITA) and had to replace the rear control arm mount. Luckily I was able to dump it before the stupid thing broke in half. I was looking at an 08 Z71 and made the guy take a ton of pics underneath before I even looked at it.
