If you don't want to repair it and can't be bothered to break it, claim on the insurance for a writeoff, buy it back off them cheap and then sell it to a breaker for a profit. I guess the only issue is loss of no claims bonus unless you've got it protected.

Or you could not go through the insurance, get it repaired out of your own money and then it won't be on the register. It doesn't look too bad to me.
