correct me if i am wrong but why do audis have such a good reputation for there body work quality i was washing my car today it is an a4 x reg 2001. and i noticed a few rust bubbles on the bottom of the drivers door about 3 inches up so i gave the car a good going over and found the same problem on all the doors and the rear tailgate. is this unusual. my mate at work as a r reg renault megan and his body work is totaly rust free what pees me off is i care for my car it gets regularly polished but hes as never seen a bucket of water let alone polish. have i been unlucky or are there more youngish audis out there with signs of rust
