Incidental accident, total economic damage, liquidation?

Hello. Who can give me here any tips and advice. Would like to receive preliminary information. Thank you! I was driven by someone at the traffic light on the back. Only damage to property. Police took on accident. Opponential insurance has already been reported damage. This assumes damage of approx. 2000 Euro. My workshop has looked at the car once. At the back everything pressed in, trailer coupling totally warped, apron away, spare wheel bay totally warped etc. vehicle still drives, however I only drive to the workshop. Damage approx. 5000-6000 Euro. My Corsa D EZ 2009 already had a hail damage 5 years ago (not repaired). Comparable vehicles are still worth approx. 6000 Euro (without hail damage). With hail damage the vehicle (without this rear damage) would still be worth approx. 3500 Euro. Question: I assume that the evaluator effectively. Total damage shows. But from which values one assumes here? Repair costs are actually clear. About 5000-6000 Euro. But v What is the current vehicle value going to be? And how much would the residual value be? The problem is that I have no fault and there is no way to buy this vehicle! (Corsa D without climate, with AHK, with Parkpilot, with seat heating and steering wheel heating in white) What will I expect? Thanks to
