MCR made a roof top spoiler for the Mk2. I found one 2nd hand never fitted, never painted, not long back, did the deal at Â£50 and then he decided not to sell Then found one on here in right colour, but once it's on the screen, you cant get it off to resell!
It's expensive new! And takes a lot of time, effort and swearing to fit. Also needs quite a bit of filler.
