When’s the accident car?

Hello together, have a car, what I want to sell. When you wanted to transport it, a mistake happened to a friend, because this day was exhausting, nerve-exciting and went many hours. Instead of driving forward, the reverse was in it and he bounced against the house wall. It was 80-100 cm and of course it rummed very much. Meanwhile the shock processed, although it hurt to see this tin wound. By the way, nothing happened to the house, wouldn’t be that bad, because is not a foreign property and you have craftsmen in the circle of acquaintances. But the before almost from the outside flawless vehicle just caught it. Did not happen on the road, but on the yard from the property. Came to the paintmaker, made everything chic and is almost finished. He was interested after a short time and asked what you would like to have. He then sent pictures/information that the car starts from a certain amount, but there is a guarantee on it with some and he sees the car as an accident car. In addition, he listed other things that are partly fixed in the next 2, 3 weeks anyway and understands of course that he wants to push the price down and clearly earn what about it, but I don’t want to spoil this great car either. Is that an accident damage or at least a slight accident damage and I have to state it as an accident car? Because if I sell it, I don’t want to give any wrong information. , wasn’t affected by it and did not suffer any technical damage – was professionally done. No person was injured at that time. For minor damage it’s probably too severe, isn’t it? Maybe someone can answer me?!
