Only 65,000 plus miles on this CTS. Took it to get a rust spot I could see on the outside of the rear fender fixed. When the body man took the wheel off to take the fender cover off, it was full of rust. He was afraid to start repair as he was worried about cracking the frame, it was so bad. He advised me to get rid of it? It was that bad. I’m wondering if there were any other complaints about this. A few years ago I had to have the trunk fixed for rust also. I'm sad and upset about this and not sure what I’m going to do as we can’t get a new car or even a used one. To top it off just got new brakes !
