My car was being repaired for a previous hit and run in a car park, after a drawn out process where we managed to track down the driver via CCTV and the police. We managed to agree that the hit and runner's insurance paid for the damage. Not necessarily important info... But it's taken a long time to get sorted and been fairly frustrating.
So my car was on its way home after being in the repair shop for a week and on the way here (being driven by the accident repair centre delivery driver) and someone has driven into the back of it. 
Whose insurance covers this? If the 3rd party driver admits liability surely they'll cover everything, but will I have another no fault claim on my insurance (somehow would seem unfair) or does this all go through on the accident repair centre's insurance?
I just wanted my car back and to draw a line under the past 6 months... But here we go again!
Any advice/ help gratefully received!
