The ruler's collection of over 300 luxury cars, including one purportedly gifted by Adolf Hitler, is housed on the grounds, while a fleet of private jets, including a gold-and-blue Boeing 737, sits nearby. His family also owns a private army. (Photo/ Agencies)

While the estimated family fortune is pegged at $5.7 billion, the true extent of Sultan Ibrahim's wealth is believed to be much beyond that. (Photo/ Agencies)

Among his holdings are a 24% share in U Mobile, a significant cell service provider in Malaysia, and $588 million worth of further investments in both public and private businesses. (Photo/ Agencies)

In addition, he possesses $4 billion worth of land in Singapore, which includes the large Tyersall Park neighborhood next to the Botanic Gardens. The Sultan's strong cash flow from share and real estate purchases has allowed his investment portfolio to grow to $1.1 billion. (Photo/ Agencies)

Sultan Ibrahim has an impact on Malaysia's economy in addition to his own wealth. As a gatekeeper for commercial prospects, especially for the Malay community, he has collaborated with Chinese tycoons on significant projects and been instrumental in their success. (Photo/ Agencies)
