i no its sounds daft, but i thaught a 1.4 with the gti bumpers etc but not sure if they fit, but my brother is in a group 16 car aswell, a 2 litre turbo astra cabroilet with only about 2 no claims bonuses and his was £1800 so a thaught it might be £2000 - £2500 on my mams insurance for me. im 100% positive it was a gti in candy white witht hem monza wheels, with the tartan interior etc, i didnt see the mileage but 99% it was an 07.
