Car dealer you say, no wonder the mods post raped you.
Yep red is a bitch to keep lookin good but DAMN they do look crisp when clean..
Mate has an Edition 30 DSG which has had to have a mechatronics unit replaced!! £600 iirc.. Although his was a dealer purchase and under warranty.
Put me right off dsg but I would deffo get a Warranty direct policy if buying a private sale dsg motor..
