I currently drive a 5-speed manual B6. The engine was replaced last year with only 110000 km on it, but the body is rotting. In particular, the groove on the roof. I've had is prched before for about $400, but it is bubbling again. I have the opportunity to pick up an automatic B6 with a mint body, but a blown a transmission. If I already have a manual car for parts, is it worth doing the swap, or should I just cough up the $1000 for a good body shop to stop the rust once and for all.
