Hi Joe,
The part we were investigating this morning is the Mk5 R32 part # 1K6 807 433 C GRU (which looks identical to the Ed30 but I can't yet guarantee it's exactly the same re fixings) - It's called a "spoiler" and will cost me £138.20+vat (approx £160). It comes primed ready to paint.
The R32's lower part, available separately, is called a "tail pipe trim" # 1K6 807 568 9B9 and comes Satin Black and is obviously only appropriate for the R32 exhaust configuration. Costs £73.63+vat.
I'm already being given favours on the overall job and cannot reasonably expect any further discount from buying two. Surely all VW dealers charge customers the same prices for parts but may individually give discount or not.
My dealer's bodyshop always carefully matches paint to each individual car - Very much preferred!!
