Total economic damage?

Hello you, I’m a little overtaxed. I had someone drive into the passenger side yesterday – she wanted to park out and didn’t see if anyone was coming. I should get a quote now to see if we have to regulate this privately or switch on the insurance. The workshop today said she couldn’t issue me a correct estimate without an expert, because the damage looks like an economic total damage at first glance. I don’t know how far the damage is worse now or looks worse, because it’s already broken there. I don’t have a plan to do what I’m supposed to do. I don’t know how far the damage is worse now or looks worse, because it’s already broken there. Is that important? I don’t have a plan to do what I’m supposed to do. I need to know how much more, because he can’t estimate it himself, but I mean to have heard that my Corsa C is still worth about 1,200 and the damage is about 1,800. Car for 1.5 years, until I have finished my studies and can afford another one. A friendly car master thinks I should let myself privately give 400 euros and he brushes over it. (He has seen the damage in a photo) The workshop said I should let the expert come. But as soon as we turn it on, it will automatically become an insurance case. What if a total damage is detected? Do I get the value of my car and have to buy a new one? do I have the value AND my car back? Can I still take off with insurance and workshop despite the total damage, that the workshop and only a bit of beauty repair and save the insurance as well? I’m afraid that after the report I’m standing with 1,200 euros in the hand and have no car anymore. But I need the next 1.5 years one and can pay NIX on it. What do I do now? Turn on opposing insurance or privately regulate it? And am I here about Right at all?
