Hello, who can give me a hint. For years there is a BMW in front of the house in front of an acquaintance. Everyone tries by note, people in the house ask, etc.. were so far unsuccessful. It is also no license plate mounted. The only thing I got out is the frame number. My question is it possible as a private person by frame number to find the owner of the vehicle so that I can ask him if he sells it? If yes, and how? Thanks already in advance. Greeting
