Welcome along! That looks
VERY cool.
Really depends on your budget fella. Are you after a early GTI or a late Edition30 or Pirelli? Do you have a price for the car and seperate amount for mod's? Are you going for "show" or "go" (or both). Can't see Air being cheap, a fair few on here have it so worth a look around in the "members rides" to get some ideas.
Candy GTI's are sought after (for some reason) so there are usually less of them about and probably more money as well. I say go with a Tornado Red Mk5, tiss the fastest colour!
Have a look through the "For Sale" section, you may find what your after and buying a car from a forum Member is a good thing IMHO as usually a forum member will be an enthusiast and will have looked after his/her car and will be well maintained.
http://www.mk5golfgti.co.uk/forum/index.php/board,53.0.htmlShould be a fair few about on 18" Monza 2's, but if you find the perfect car for you without them, they are always about to buyon the forum (some on here now), either the Monza 2's or the latter (much better looking IMO) Monza 2 shadows. Monza's can be refurb'd to look like the shadows too.
Happy car hunting!!
