Angela18666:Could someone please tell me what "Salvage Costs" iinvolves
You need to ask the insurer and, perhaps, ask them to pay all costs.
Generally speaking, if you want to scrap a car, you phone up a scrap yard and, as long as at least two wheels go round, they will collect it and make a payment. This payment may be just £30 for an old MOT failure, but there's certainly no costs to pay. There will be costs for moving the vehicle from the accident to where it is now and there will be storage costs but, in my view, these costs should be paid by the insurer.
I expect you will need to enter into negotiations until you come to a value (and deductions) that you feel are reasonable.
