Accident, not to blame, how best to handle it?

Hello, my daughter has someone rushed into the passenger side. Police on the spot, the accident opponent has received a warning. Opponential insurance (HUK, there you can see what super service is) sends a letter on the same day, confirms the entry obligation. And of course suggest their all-round service, i.e. they handle everything for us. Naturally very nice and extremely customer-oriented, we would not have best contacts to body builders and paintrs… How do we do it now best ? We believe: 1 Kovo collect from the contract workshop, possibly costs for this 2 these submit with the opposing insurance 3 deduct the amount of the VAT take 4 usage failure get pauschel 5 car at the brother-in-law have repaired is that correct? Of course not, undeclared work is never correct. But neighborhood help is already, or . My daughter is Azubi, and there is crownish ebb in the cash register.
