My cousin’s accident – can I buy the car or keep it?

Tach people, my cousin with the same last name had an accident with his car without fault. The selected expert came, and examined the car. In principle, these are metal acheeds, on fenders, rim, bonnet and headlight. Absolutely no damage. The car was now declared as total damage. Replacement value 3500 Euro, minus residual value 550 Euro, are 2950 Euro which he would get. The Gutacher meant, if you know someone the self-stä In other words, from the point of view, otherwise the opposing insurance company would still want to see the car, or offer it to the market itself, so that more money is generated, so that the insurance has to pay less from my own pocket. If I can buy the car as a cousin for 550 euros, however, would not be a self-employed person, i.e. private purchase. What does it mean if a car is spent as a total damage? Could even my cousin the W if he would let one or the other do it? Even if he would pay off on a total damage basis? Can mab keep the car under these circumstances? Replacement period 12-14 days and 59 euros according to expert opinion, is there ONLY, if one buys another vehicle? Greetings
