Try greenlight insurance, they cover performance cars (you might get away with covering an 8v gti

) they used to cover my 275bhp leon cupra r for £500 and im fairly young and from croydon. I am pretty sure i had an agreed value with them for £6,000.
Now im in the golf im only on third party fire and theft so even if i do have a crash im unlikely to get anything from insurance anyway. If the other party was at fault in a crash i think elephant said its worth £300. A shame really as its near mint with 51k on the clock and can guarantee you wont find one for £300 without rust and the low miles i have.
Heres hoping none of us crash
