If you were rich enough to drive any car you wanted, absolutely any car, and money is no object, what would you go for? A Lambo, Bugatti, Merc, Aston, how about something outrageous like a Formula 1 car.
But what if you were truly rich, not just "getting by" like that Bill Gates guy, but truly rich. The Sultan of Brunei is the richest man on earth; he is not counted on rich lists because he does not earn his money it comes from his tiny country's oil reserves which are basically his. Estimates of his wealth pop up from time to time but the truth is no one has any idea how much cash he has.
