If it's practical for you, you could buy back the salvage, break it and sell it. Only tell them this after you've agreed a price to settle though.

Beware that they may well count their first offer as the start of your X days left of car hire.  Visiting from DISCO3.CO.UK

I have no desire to try to fix it, the roof is rippled apparently, needs a new shell.

My first conversation with ins co is to point out mine was a LR approved- warranty car.

No, I meant break it up and sell the good parts. Obviously, it depends on what's left of it but the price would be according to that. You should be able to make some extra cash out of it if you are in a position to do so.  Visiting from DISCO3.CO.UK
