You are entitled to be put back to where you were, which means the car should be back to the condition it was in before the collision. An economic write off is just that - the vehicle costs less to repair than replace, and this is likely to have been the case with your vehicle. The problem is that the repair was not up to acceptable standards and you have independent evidence for this. A second go at the repair may well take it beyond an economic repair so they might be more amenable to suggestions that they replace it.

If you have not been put back to where you were, then you can issue proceedings (or threaten to) to ensure the car is either repaired or replaced. Alternatively you can make a "diminution of value" claim for the amount by which the car is worth less than what it would have been if the accident had not taken place. We have an accident specialist who deals with these type of cases and I can put him in touch if you wish. He normally likes to discuss the issues on the telephone so it would be useful if you provided us with a telephone number.
