wait till they asess it mate, you'd be suprised what is repairable....

I got a really low offer on a rear end shunt (landrover in back of me) and I just sent the 3 highest autotrader listings for the same car and got £100 lower than the lowest of the 3, with no agreed value or anything on my car.

However you're claiming on your own insurance as 1 car incident so pushing for a high payout will push up your premiums, especially if your into fast fords.
