Financed car after half a year accident car.

Hi people, had a traffic accident last week and I am at the thing as a damaged person. Door, threshold covering as well as side wall was damaged with me, the property damage amounts to 9000 Euro plus. Merkantiler inferior value of 1,500 Euro. I am totally at the doubt. Did the vehicle buy only last year in May for 38,500 Euro at Mercedes with a 3-way financing. The car is now an accident car. What possibilities do I have now or what do you recommend me best? I find my car great and would have liked to continue driving the car, however, the door is changed and the entire page is repainted. The car after the condition to continue driving with such an intervention and as an accident vehicle totally bugs me though I can’t do anything for it. What would you do? Mercedes only said: “We can buy the car normally and dissolve the financing” but they do not come to meet you. Drive a Mercedes C Coupé 2018 C300.
