If your car is a cat D or Cat C insurance damage write-off and you take the money then you cannot stop it being sold by the insurer for salvage and subsequently repaired. You can, of course, refuse to allow it to be written off and argue your own case for financial compensation for the damage, then arrange to have it repaired yourself, which you might be able to do for less money than the insurer was quoted. Your legal right is to sue the other driver to put you back in the position you were in before he did you the damage. But Clark v Ardington (Appeal Court 19-4-2002) determined that financial compensation to the market value of the car would put you in that position. You have no automatic right to insist the car is repaired. Its dealer retail value is £6,700, trade value £4,875.
