I'm glad that you still saw that it wasn't a mock-up car, I believe that then you took a closer look at what luxury cars actually are 🙂
You know, only a rich person can have a collection like this, and Rainier III was that.
If you looked at the posts I linked, there is also a part with the Formula, as well as the palace on the Rock where he lived...
And there follows just one more post from Monaco, which will show in pictures and words all the luxury and wealth not only of the princely family, but of a large part of the inhabitants of Monaco.
