LOL, did you not know that your GT is a group 17 insurance. The same as a Impreza Turbo,V6 Laguna,ST200, GSI etc etc!!! Phone up an insurance company and ask what group it is. I think you know why its so expensive, its that paint LOL

. I can get insured on my Sri for £1400 (im 19) with a full exhaust system/header, cold air intake (same HP as a GT, if not more).
