Cheers for comments peeps.
The silver is satin silver metallic. Lp7z I think, but don't quote me on that lol
Funny you got a black one geeman, cos that was my first choice and didn't hold out for one. Altho in the end, I think I prefer the silver and the way it looks on the car.
Funny thing is, when I bought it, I didn't realise the silver GTIs were pretty thin on the ground, so I suppose that's an added bonus as well.
