but expect it to be expensive, being a V8 and you being under 25, surprised they even offered to insure you...
I had a quote for a V8 SS Ute once and that was goin to be on "special conditions" and even then it was still $2400
I doubt you will be getting cheap insurance until you are actually over 25. Esp as soon as the insurance companies get wind of the fact a car is a v8 or turbo
