£595 with all mods declared (inc RS turbo) is not a bad quote, but, if the car is written off the mods are not covered, so the 3-4k spent would be lost.
Currently with Liverpool Vic, bit more expensive but will replace mods.
Just waiting for a qoute from Greenlight

ive just been quoted £567 with protection from Noel Dazzley with all mods too,wife as named driver with a sp30
