He is the 29th (and current) Sultan and Prime Minister, Defence Minister, Finance Minister, and Head of Religion of the Nation of Brunei. The majority of his wealth is sourced from oil and gas development.

Forbes magazine ranked Bolkiah as one of the richest people in the world, with a stupendous fortune of $20 billion. He is a lover of cars. His fortune enabled him to collect models that are not only expensive but also rare. When Bolkiah collected 300 cars, many people thought that he garnered an impressive collection, but Bolkiah continued to spend his money to quench his thirst for cars.

He has more than 600 Rolls-Royces, 550 Mercedes Benzes, 450 Ferraris. Within his collection of cars, the Sultan’s collection of Ferrari F40s, McLaren F1s, and Rolls-Royces are particularly notable due to the rarity of the vehicles and their value. 

It’s said that during the 1990s, his family accounted for almost half of all Rolls-Royce purchases, adding unique cars to their own collection and bulk-buying.

Not just that, he also owns every Formula 1 car that has won a championship since 1980. Incredibly, the iconic brands Porsche and Rolls-Royce once combined their designs to make a one-of-a-kind hybrid, just for him!
