I'd say this represents reasonable value given that a straight one is 30-34K.

It really is pretty minor damage and I don't think the chassis leg will be bent given the crumple box is still intact and the shut lines look good and no airbag deployment. With new parts £5k to fix less if s/h parts used. If one can do their own labour then even less.
If it's unrecorded then there will be no complications when selling after the repair is complete.
