Going to look at an 07 GXP vert, stick with under 3k. When I read some posts on how hard parts are to get and where to even bring the car for service kinda scares me but I've always loved these roadsters. Anyway, what is quick list of things to look for when having them inspected for purchase? Also can we still bring these to GM? Is there any new age mechanics at the dealership that know how to fix these cars? Thanks for any info.
