The annoying thing was that I actually warned them about the plastic primer, and they hmmed and arhhed. In the end, I told them if painting plastic was so difficult, then every Golf, Polo, Toerag, etc would have paint peeling of the front and rear bumpers, and they couldn't follow up that one.
Re the ident car, mine has already been back to them 4 times, at 240miles each visit, each time, they keep saying they fix the problems, each time I get it back, still the bl00dy same! Heads will roll - OK, letters will wing their way to VW UK and VW AG if they give me any more grief!
