It was 5 or so years ago, so I am trying to dredge up my memory of exactly happened. The dealer was Mercedes Coldstream. I am pretty sure that their service advisor simply gave me the contact details of the approved body shop in Newcastle and I contacted them direct. I had to take the car to them for inspection and they forwarded a report to Mercedes who gave the go ahead after a few weeks. I even had a newish C220 Estate to run around in for a couple of weeks while the job was being done. So all the dealer did was give me the contact details. The body shop took it from there.
