Fianziel total damage! What now?

Hoi, I had a wild accident without wild contact. I braked on the animals, a few decimeters in front of the car jumped away the WIld pig, and since it was a curve + wet + leaves I slipped into the guardrail. With about 10km/h. harm: www.more4pc.de/argh.JPG so: Now it is doubtful whether the insurance pays. Expert was there today, and thought it would be a financial total damage.What now? Let’s say residual value of the car (before the accident): 1500€ Repeating costs: 2000€ Car value now: 100 Do I get the 1500€ and can I keep the car? Do I get the 1500€ and have to give it? Do I get the 2000€ and can I keep the car? Or do I get the difference between old and new value? (500€) Since the car was previously driven by a pensioner and has no repaired damage + a top engine, it is worth pers. more than the residual value. Would then rather take the 500€ and fix that somehow. mfg röwe
