IMHO:
R32: Beautiful vehicle, beautiful V6 engine, with 4 wheel drive when required. Road tax very expensive.
ED30: Has KO4 turbo and other engine improvements, pushes 230bhp stock. Styling touches as you mention. 'Higher spec' you mention - depends on what the original buyer ordered - xenons etc., same as a GTI.
GTI: Lovely car and some people feel that a remapped GTI betters an ED30, possibly due to a little more lag with the KO4.
I'd say you're looking at a GTI or ED30, a nice dilemma. I've seen a few horrible ED30's BTW - ragged/crashed so be careful!
Common faults-do a search.
Good luck with your quest!
