dont forget to consider the R32.
All three MK5 cars are very good - I have only driven my ED30 but got that as opinion suggested it was the best all rounder out of the three, but it is horses for courses, the Gti will be better in some respects for certain people because they dont like the styling of the ED30, dont want to pay the premium or prefer the 0-40 grunt of the k03 and the R32 will be preferred by some people due to traction, soundtrack, 6 pot etc.
