aland - your in exactly the same position I was in - I had a lovely GTTDI nearly bought from a dealer when I was 19 - it was a minter with on 20k on the clock and I couldnt get it due to insurance
The following week the dealer phoned me and said he had taken a part ex in (the 2.0 GTI) which was a lower insurance group and spec'ed the same as the GT...my GTI was a nice car has to be said - one mature owner from new (still on its original tyres), special order sunroof and climate together and Turbo wheels...I miss it greatly!
