I've dropped the claim on my car already, they said I can come back to them and claim if it turns out it'll cost loads to fix once it's properly checked out. Obviously the other people involved will claim against me though.
Happen that I do end up claiming though and they Cat-D it, what happens then? Other than the resale value going down, are there are costs to consider once I've fixed it?
As a course of action this makes no sense - get back on the phone and tell them to include your car. Let them know you want to buy it back if they write it off (they will). You then agree a value and this will come off your payout.
Do this and you will have a few hundred quid in your pocket for repairs (unless you have a silly excess). Go down your road and you have a car that will cost you a few hundred to put right plus the increased insurance premiums for a few years anyway with no financial recourse
