Hassan al-Balaieh Mousaeddin Waldouleh, Approximate fortune: $ 20 billion
Sultan Brunei, Hassan al-Balaghih, has been King of his country since 1967 and has full control over the affairs of this country. He is also prime minister of his country and is more interested in the car than anything else. He is said to have between 3,000 and 6,000 cars, and he usually likes exclusive cars that are hard to get. Of course, he is not interested in land travel, so he uses his exclusive Boeing 747 for his travels.
