I was wondering if many of you guys could help here! I have the GTI trim on my car and i was just wondering how bad could the rust be behind it?  I can see on one of the front arches that its a bit chewed away but i was wondering what kinda condition are the bits hidden along the sills at the bottom of the car?  Also anyone had there arches and that rebuilt and sprayed, if so what sorta price did you get?
Cheers
Ben
