as above, down to your needs.
Personally I chose normal gti for a few reasons. I prefer monza 2's over the edition 30 wheels, like the black side skirts against candy white paintwork, love the bucket seats it come with over the half leathers in edition 30.
Down point is the rear bumper though, needs sorting lol.
Main bonus about edition 30 is the engine imo. But with this it increased my insurance by couple 100 so decided against it.
If you just want something that looks nice and sounds good, r32 best choice but mpg is worse i believe.
If your not bothered about out right power, as gti is still quick enough for normal roads then id just see what money you have and whats on the market when your in position to buy. Its a buyers market at the moment so some bargains to be had
