Possible total economic damage 🙁

Moin people. I hit a guardrail last week with my Mazda 323f bj (Bauj. 2002). At first I thought that nothing happened, because the impact was almost not felt. When I got out, I saw that a headlight was scratched, the bumper was pressed in about 1cm under the bonnet and the bumper was scratched. (at the guardrail there was no damage) Now I was in a workshop and the damage amounts to about 21 00€. Hardly imaginable. I thought a new headlight and the bumper is directed and good. Well, the big problem with this story is that according to DAT my car is about 220€ worth or was before the accident. Now I just hope that it is not a total damage! How do I have to behave now, or how should I regulate the damage? Do I have a 10-year-old car repaired? Do I calculate after cost estimate and try to get the car back in fire again at low cost? in case of a total damage I will only get a minimum amount (with the car) or? Well, it depends on the residual value. But since the car is only a little whipped up in the front, it will certainly not be so small… And the calculation of the replacement value- residual value = sum Or? Greetings Akkmann
