don't give up on the insurance just yet. I take it you've tried Adrian Flux? Also try Keith Michaels PLC. I got some wildly varying quotes from all over the place for both uk and import cars. Tesco who were my current insurer at the time wanted about £1,500 plus a tracker! Keith Michaels was about £600. Oh and try RAC as well. They gave me the best quote but unfortunately I couldn't insure with them using the vin number and didn't have a reg number at the time or I would have used them for definite.
