So it's going to turn out really expensive :(
You'd think, but keep your eye on eBay for some deals. I bagged an R32 rear bumper (genuine, brand new) for £100 less than dealer, got the reflectors (which should be £16 each) for £10 for both... Bit of patience can save loads of £££.
Also, get yourself over to the Wanted section on here and put a plea out, I'm sure someone, somewhere will have the bits collecting dust in their shed. You don't ask, you don't get!
