So I am looking at getting a 2002 Grand Prix GT today.. 2 door.. Has 84,xxx miles on it and the seller wants $3500. The underbody looks amazingly clean for being a midwest car and the strut towers and rocker panels have no damage. It had a fuel line break and caused an engine fire, but it was put out fast enough that the hood liner didn't even burn. It was put out with a fire extinguisher, so I was told to be aware of rust issues in the engine bay. The original owner gave up with it and it sat for two years. He sold it to the shop I go to and the guy did a full valve job on it and fixed the running issue. It runs now.
Really the part that gets me is the frame. The factory mount points are still almost perfect. So would you bite? I can't talk him down cause someone else wants it for the same price.
