3. Boeing 747-430 owned by Sultan of Brunei – Price: $233 million
Usually the first name that comes to mind when talking about the world’s most ridiculously rich people, the Sultan of Brunei went over and above the standard purchase price of a 747 by a whopping $130 million. Every single penny of this was spent on lavish luxury and beautifully unnecessary adornments. How unnecessary? Well, let’s just say that every sink in every one of his bathrooms on board is made of solid gold. There’s so much crystal and gold around the place that you’d be forgiven for thinking you are actually flying in a jewelry store or museum.
