been in same position, kept stating that i had to get the car fixed, it was valued at �250 quid and that was the first offer they gave me. i sent it clips from autotrader / loot showing that i couldnt reaplce the car for less than �500 and the insurance company paid out �500. i got the car through an MOT and back on the road for �600 total within 2 months. it can be done, just keep saying that you don't have a choice. it costs the insurance company a fair bit of money to get rid of a car, they will let you dispose of it for that reason alone, but if you can get it through an MOT you can put it back on the road, just dont expect anyone to want to buy it! good luck
