2018 Peugeot 208

I have a Peugeot 208 at the panel beaters with parts delayed indefinitely. I'm now trying to negotiate a cash-in-lieu payment with the car sold of for salvage as is. Damage is primarily to the back (was rear ended) and some damage in the front right (was pushed into the car in front of me). The car is still very new with a mileage of 19k and engine still in perfect condition. Let me know if you can help
