Theres alot of people in this thread that seem to be paying silly money for their insurance. Ive got a 1.3 mk2 and the cheapest qoute ive had was £560 with my mudda as main driver (going to have to change my log book so i aint fronting). Once ive passed my test I aint looking to pay anything over £800 quid, I could try classic insurance but it has to be 20 years old (its 19.5lol).
As for a mk5 GTi at 17, i think your mad, or your parents must be mad, I know a guy who had an m3 at 17 (mummy and daddy obviously). I suppose if mummy and daddy are paying for your car and paying for the insurance, then just milk it, but if you crash, i bet they wont pay it after that.
