I always find my father-in-law a bit funny, because he is so cheap when buying things like a grill or tools, but has spent massive amounts on cars in the 15 years I have known him.
I will never understand the cost of ferrari / other luxury cars. Sure it is fast but that just means that you are more likely to get injured or at least fined. In my opinion a yacht is more interesting toy for rich people. But maybe this is because in the seas there is not many humans. As far as I concerned cars are items of mass production and more expensive ones are no better than cheaper cars. So if any car costs let's say 20+ k it already seems like a rip off to me. Even if I could drive I and had money to spare I would probably buy a cheap car. I believe I heard that using a car for a year or two it already loses considerable part of its value? Not to mention all the necessary insurance, repairs and technical checks...seems like a total waste to me.
I don't get the cost of cars either - though perhaps if I had so much money I didn't know what to do with it, I might buy fancy cars also.
