While car collecting is a hobby many enthusiasts enjoy, the wealthy takes it to a whole new level many can only dream about. Thanks to their seemingly unlimited resources, famous and wealthy car collectors have been able to amass some of the rarest, most exotic, and most valuable cars in existence that turn their garages into treasure troves. There are many famous car collectors throughout automotive history, from actors and musicians to business magnates and royalty. Most car enthusiasts know about Jay Leno, Ralph Lauren, and Jerry Seinfeld and their impressive collections. But none of these is as remarkable as the Sultan of Brunei's collection.
