Try competition car insurance, iu'm 27 with 1 yaer ncb and agreed value at 9.5k and 800 comp in ch43!!

Mate of mine just turned 21 and he's running (or will be when he gets it back from Mr Hadland!) 450 ish bhp 2wd and he's paying 1500 comp all mods declared

The number is usually in the back of the demon tweeks catalogue, give them a call!
