5. Sheikh Hamad Bin Hamdan Al Nahyan
Affectionately called the ‘rainbow sheikh’, Sheikh Hamad Bin Hamdan Al Nahyan is a member of the ruling family of the United Arab Emirates. His love for the rainbow colors earned him the name ‘rainbow sheikh’, and these colors can be seen in many of his investments, his car collection included. According to estimates, he is worth $20 billion, and it is only but natural for the sheikh to show his love for powerful and exotic cars. He owns more than 400 cars and trucks, and most of these vehicles are displayed at the Emirates National Auto Museum. He owns a number of Mercedes S-Class vehicles available in rainbow colors, a Rolls Royce Phantom, Volkswagen and 1972 Land Rover Shortland. Another interesting item in the collection is the Dodge Power Wagen, the largest truck in the world.
