? Accident damage, hit-and-run, Parkrempler

Hello, someone can give me an assessment: My ’93 Vento was parked on the street with my parents when it rang in the evening (it was already dark). A neighbor was there and said that he and his son had been watching a lady park in front of the Vento. And then drove away. My parents called the police. The “accident” was taken up and I received two letters from the police. Once an explanation was drawn where witnesses, causer and return point were . And then a hearing sheet, where I should express myself and ideally indicate something about the level of damage. And then send it back to the police. In fact, it’s the case that on the information sheet “punishment” is ticked and the driver probably says that she didn’t drive against it. I can’t tell myself exactly what could be damaged, because the Vento in the field of impact observed by the witness has a lot of scratches. What should I do now? Painters go and have an estimate made (but it’s chargeable)? As I said, you can’t say exactly which scratches come from the impact car. He could certainly create a cost estimate for me, on the basis of which it would be billed (is that possible in this situation at all, if the other one says she didn’t drive against it?), there are enough quirks there. And then, if necessary, let some other places be repaired with it. Or is one left then If necessary, sit on the costs or have to order an expert, who could probably also not detect any damage due to this augmentation? Moreover, the value of the ventos should only be a few 100€. Thank you.
