Hello! unfortunately, someone with an old Chevy pickup with an open flap and trailer coupling at the back drove up! My vehicle was also rented on the premises on my company premises. It is backwards on:/. I had no comparable case. Since no people came to harm we did not notify police. I have the insurance documents. My rear bumper is completely over exhaust has a small Macke and scratches (I don’t want to worry about a change you can hardly see) Reflector Left broken tailgate slightly pressed on the fold Diffuser broken Otherwise hardly anything to see. Do I now have to contact the insurance of the counterparty itself ? How high should the damage fail ? Greetings
