The Sultan of Brunei owns 7,000 vehicles worth over $5 billion, which is considered the largest and most valuable private car collection on Earth.
During the 80s and 90s oil boom, Sultan Hassanal Bolkiah and his brother, Prince Jefri Bolkiah, used their wealth to finance a collection that included one-off models created specifically for them from high-end brands such as Ferrari, Bentley, and Rolls-Royce.
In fact, the Sultan of Brunei holds the Guinness World Record for the largest private Rolls-Royce collection, with 500+ vehicles.
Several vehicles from the collection have been neglected in recent years, but the collection still holds a wealth of classic automotive history that only a few people will ever get to see.
- The Royal Family of Brunei owns around 7,000 cars.
- Prince Jefri Bolkiah was the primary financier of the bespoke vehicles, commissioning the majority of them through companies such as Pininfarina & other coachbuilders.
- Noteworthy vehicles include six Ferrari F90, multiple McLaren F1, and the prototype for the Bentley SUV.
- Recent leaks & tours have indicated that some of the collection is in a state of disrepair, while other vehicles have been relocated to different locations or restored.
- The collection has been divided into several climate-controlled garages across Brunei and is kept under strict security.
What is the Sultan of Brunei’s Net Worth?
Sultan Hassanal Bolkiah’s estimated net worth is around $30 billion in 2025, which makes him one of the wealthiest royals in the world. The majority of this wealth is based on the oil & gas supply in Brunei, as well as the amount of land that is owned by the royal family.
Brunei has around 500,000 citizens, which allows a great deal of money to be accumulated and managed, as well as through the Brunei Investment Agency, which has approximately $70 billion in assets.
During the period from the early 1980s to the mid-1990s, when oil prices were at an all-time high, this wealth was used to create a very large collection of luxury cars.
As a result of the large amount of money being earned by the Sultan and Prince Jefri during this time, both of them were able to spend large amounts of money on both standard production cars and custom-designed cars.
If you thought Jay Leno’s collection or Mike Tyson’s car lineup were impressive, wait till you see what the Sultan and his brother have collected throughout the years.

1. Ferrari F90 (1988) – 6 Units
For 17 years, Ferrari kept their F90 project a secret. For the Sultan, Pininfarina constructed six Testarossa-based supercars with advancements at the time and with modified radiator locations. In 2005, Ferrari publicly acknowledged the F90 as one of the most enigmatic Prancing Horses produced.
2. Bentley Dominator (1990s) – 6 Units
The prototypes are two decades ahead of the current trend of luxury SUVs. The Sultan commissioned Bentley to create six 4×4 Dominators in complete secrecy, which laid the foundation for Bentley to create its Bentayga. The only record of the existence of these vehicles was through paparazzi photographs of Dominators heading to the Sultan’s private airstrip.
3. Ferrari 456 GT Venice Series – 7+ Wagons, 4+ Cabrios
Prince Jefri ordered an entire family of bespoke 456s from Pininfarina, including shooting brake wagons, cabrios, and sedans. Each car was rumoured to be priced at $1.5 million, and that’s why the wagon format is the only factory-backed Ferrari estate in history.
4. McLaren F1 – 7 Remaining of Original 10
The royal family placed one of the largest single orders of 10 McLaren F1s at the time of the car’s launch. Over the years, some have been sold, but reportedly seven McLaren F1s remain in the royal family’s garages in Brunei, along with several other hypercar legends.
5. Ferrari Mythos Concept (1989) – 3 Units
Designed by Pininfarina as an over-the-top Testarossa prototype, the Mythos was a show car and was never intended for production. However, it was rumoured that three vehicles were sent to Brunei, one of each colour: red, purplish-blue, and black. These are the only known private examples of the Mythos concept.
6. Rolls-Royce Custom Fleet – Over 600 Total
Probably the most talked about car in the Sultan of Brunei’s collection, Rolls-Royce. In fact, he has the largest private Rolls-Royce collection ever assembled. Includes hundreds of bespoke limousines like the Royale, Majestic, and Cloudesque models, plus the famous 24-carat gold-plated Silver Spur from the Sultan’s wedding.
The Silver Spur is also considered the most expensive bespoke car in his collection, valued at around $14 million due to its 24-karat gold plating & unique customizations.
7. Ferrari FX (1995) – 6 Units
These Testarossa variations were equipped with a Williams Formula One 7-Speed Sequential Gearbox with paddle shifters. This technology was used for many years before its introduction in a Production Vehicle. Six were sold to Brunei, and one to a museum in California.
8. Custom Ferrari F40 – 8+ Proprietary Produced
Almost all Ferrari F40’s produced were delivered to clients with the same Red paint & cloth seats. Brunei’s examples came with a number of unique features, such as leather seating, custom color schemes (green, matte black, and silver), and even left-hand drive conversions by Pininfarina.
9. Aston Martin Vantage Special Series
Brunei-exclusive commissions with a very unique design & styling with additional performance enhancements from the factory. Information is still limited on these vehicles. However, they are an indication of Aston Martin’s desire to create anything for the right client.
10. Bugatti EB110 Collection
There are multiple EB110 examples in varying specifications, and they were part of the hypercar hoard, which also contains the Dauer 962 Le Mans Rides & other Supercar Legends from the 90’s.
The Current State of the Collection (2026)
Recent visits by photographers like Larry Chen reveal a mixed picture. Some are still in great condition since they were climate-controlled museum-like facilities. However, there are several garages that have not received the same attention, resulting in numerous damp and rusted cars, as well as almost all of their cars being left overnight without any protection.
Restorers have already begun their work on a few of the better-kept examples within this series of vehicles. On occasion, the best restoration is sold at auction through the local dealers.
Someone also shared images from the Sultan of Brunei’s car collection on a Google Drive folder. People have spotted some gems, such as an AMG Sprinter Van & Ferrari 546GT. Of course, not all of these cars may still be in the collection.

Final Say
The Sultan of Brunei’s automobile collection will always be regarded as the pinnacle of automobile extravagance of the 1990s. I can’t even comprehend a single person or family owning this many cars worth over $5 billion.
For car enthusiasts, this collection will continue to be an inspiration and reminder of what happens when unlimited wealth meets unlimited passion.
