The Sultan of Brunei's car collection

Long before the Bentayga, Bentley built an SUV for Brunei. The Dominator borrowed heavily from the Range Rover of the time, and six were built in the 1990s, each reportedly costing around $4.6 million. According to CarBuzz, that money helped Bentley through some hard years.

The Buccaneer is a GT coupe the Sultan commissioned from Bentley. Its engine is reportedly shared with the Continental R of the same era, and HotCars says around six were built in black, red and silver, all still owned by the royal family.

The Continental R was Bentley's big two-door grand tourer of the 1990s, and the Sultan took it further with the Continental R Superfast. CarBuzz lists it among the unique Bentleys built for Brunei, alongside names like the Java and the Highlander.

The Sultan once held a Guinness World Record for the largest private Rolls-Royce collection. On his wedding day he paraded in a stretched Silver Spur II plated with 24-carat gold, a car CarBuzz says was valued at around $14 million after the work was done.

The F90 Speciale started life as a regular Testarossa and was then reshaped to the Sultan's taste. HotCars and CarBuzz both list it, with a custom Pininfarina body over Testarossa internals.

The 1995 Ferrari FX is one of the jewels of the collection, a one-off built on Ferrari F1-era mechanicals with a completely redesigned body, according to HotCars and CarBuzz.

The F40 LM is the racing version of Ferrari's legendary F40, with much more power and less weight. The Sultan owns one. The collection also includes road F40s customized by Pininfarina in colors Ferrari never offered.

The Mythos was a Pininfarina concept car based on the Testarossa, with a wild open body and huge rear wing. CarBuzz confirms a Ferrari Mythos has a place in the Sultan's garage, which makes it one of the very few in private hands.

The Sultan had a soft spot for the Ferrari 456 and ordered many special versions. The 456 GT Venice cabriolet is finished in one-off Forest Green with a green interior and a soft top sourced from a Mercedes SL, according to CarBuzz. There is even a 456 Venice wagon.

The McLaren F1 LM is the ultra-rare racing-derived version of the F1. Only five examples of the track-oriented LM were made, and CarBuzz reports the royal family owns more than one. Ralph Lauren owns one of the few that got away.

The Nazca M12 was an Italdesign concept that could have been the successor to the BMW M1. It never went into production, but CarBuzz reports that the Sultan had Italdesign build a version for him, with the V12 from the BMW 850i.

Among the more modern cars in the collection is a Brabus G700, the tuned and widened take on the Mercedes G-Class. It appears on CarBuzz's list of cars known to be in the Sultan's garage, next to a Jaguar XJ220 and a Mercedes CLK GTR.
