I fell for the same trap mate, Bought a 1.4 Mk2b sporting before i passed my test. Got insurance for £1,500 thought okay i can live with that.......
Passed my test, Rang them up to tell them the good new's and the nice reply i got was "Congratulations, Your premium is going to go up to £3,000" I am due to re-new next year and things are looking abit better, Why dont you try Tesco? They gave me my cheapest quote.
