Thanks to ALL of you for the great advice.
Going by the majority I think 5 doors is the way to go, so therefore I should just wait and be patient (2 things I'm not that good at) for the right spec GTI to come along
I agree that 3 doors is a better looking car, I used to have 2 3dr Golf GTI's (Mk3 & Mk4) before I got into Audi TT's, but practicality is my main requirement now. As for going bigger than a Golf, I really hope it doesn't come to that as I just don't think I'm going to get as much enjoyment from driving an Audi A4 Avant or BMW 3 series Touring?
There seems to be quite a few GTI's out there, but with such varying specs, mileages and prices! I'm after the following....
must haves....
5 Doors
Black
Full Leather
18'' Monza II's
Average mileage
DSG
would also like....
sunroof
Xenons
Sat Nav
up to £15,000
I have looked at a couple, but none have been totally my spec or have just not been cared for. My 2.5yr old TT was immaculate when I sold it and I would like to find a Golf in a similar condition. I do have time on my side as I do have my wife's VW Lupo to drive around in, but after years of enjoyable driving in quick cars my street cred is decreasing very quickly!!

Thanks again guys. The search goes on.
