Hello! I'm think'in about buying a 06 grand prix gxp with 64,000 miles, its kind of a darker teal color and the previous owner put a magnaflow exaust on it as well they want 14k but i'm thinkin about offering 13.5. I'm wondering if this is priced right? or should I keep looking, also i'm wondering ifthere are any mechanical problems with these cars that are going to start showing up in the 60k mile range I should know about. Any advice on newer gxp's would be great! Thanks - Jason![]()
