I'm worried that it's a risk, too. But a lot of people buy their first car that way and are happy afterwards. It's probably a good idea to start looking for a good mechanic. But I started researching the topic, there's a lot written about it. I would even say that it is interesting. It's true that you probably can't do without the help of a professional. But now I know about the existence of the vin-code and many other things, maybe someone interested here.
