Is this the strangest car collection in the world?

Slide of You're looking at the world's largest SUV. In the lower half it's an Oshkosh M1075, an all-terrain 10-wheeler truck more usually deployed by the US Army. On top however it's a Jeep Wrangler, while overall power comes from a 15.2-litre Caterpillar diesel, good for 600 hp. It's a cool 10.8 metres long (35 feet) and 3.2 metres (10 feet) high. Oh, and it has headlights from a Ford F-Series Super Duty and rear lights from a Dodge Dart, as you do. The owner of this intriguing confection is none other than Sheikh Hamad bin Hamdan al Nahyan - and he's no ordinary billionaire. As a high-profile member of the United Arab Emirates royal family, the man known as the Rainbow Sheikh once paid to have a series of canals that spelled out his first name carved into an island located off the Abu Dhabi coast. But this vast SUV (called the Dhabiyan) is far from his only car. Indeed, it's just the latest in a long line of vehicles in his personal collection that also doubles as the country’s national car museum and Autocar paid it a visit. Considering the sheikh's net worth is in the vicinity of $20 billion (£15 billion), you might expect a building full of rare, powerful supercars. However, there are none to be found and the museum is all the more fascinating to visit because of it. It’s an eclectic collection of oddities peppered by stellar examples of 1980s tuning. Join us for a virtual tour of one of the most mystifying car collections in the world: Slide of The giant Land Rover The Emirates National Auto Museum is located in a pyramid-shaped building that’s about an hour away from central Abu Dhabi in the United Arab Emirates. After leaving the city, getting there is a matter of following the long, straight roads that cross the desert. You know you’ve arrived when you see a mammoth replica of a Land Rover Series 3 that effortlessly dwarfs a Nissan Patrol. Slide of The giant Jeep The second house-sized car parked outside of the museum is a replica of a Willys Jeep complete with a shovel and an axe mounted on the driver’s side of the body. It rarely moves but it’s drivable from a seat hidden behind the grille. At 21ft tall it's four times bigger than an actual Willys and it's certified by Guinness as the largest Jeep replica in the world. Slide of Mercedes-Benz W116 monster truck The Rainbow Sheikh has a soft spot for odd, obscure and underappreciated vehicles and he frequently makes his wildest dreams a reality. This is evident before you walk in: there is a Mercedes-Benz W116 turned into a monster truck parked in front of the museum. It was developed and built to be used but it hasn’t turned a wheel in quite some time. Slide of Mercedes-Benz R107 SL Hamad bin Hamdan al Nahyan’s fascination with the colors of the rainbow earned him the nickname Rainbow Sheikh. Many of the cars in his collection consequently wear rainbow accents, including this R107-generation Mercedes-Benz SL. Every part that’s chromed on a standard SL has been gold-plated on this example and the flag ports indicate it was driven in parades. Slide of Mercedes-Benz 500SEC by Styling Garage Hamburg-based tuner Styling Garage converted this 1983 Mercedes-Benz 500 SEC into a tuner’s dream come true during the 1980s. The modifications included widening the wheel arches, adding custom bumpers on both ends and installing a pair of gullwing doors. Slide of Riding with a falcon The modifications made to the Mercedes-Benz 500 SEC by Styling Garage continue inside with an AMG steering wheel painted white, re-upholstered seats and a new-look dashboard fitted with gold accents. The finishing touch is a falcon-shaped shift lever sculpted from a solid block of wood. Slide of Mercedes-Benz 600 Mercedes-Benz designed the 600 limousine to carry the world’s wealthiest individuals so it’s no surprise to see one in the Rainbow Sheikh’s collection. The list of famous 600 owners includes David Bowie, Elvis Presley, Coco Chanel, Josip Broz Tito, Leonid Brezhnev, Mao Zedong and Saddam Hussein. Made in 1977, this short-wheelbase example is in immaculate condition inside and out. Slide of Mercedes-Benz V123 The V123 was the factory-produced long-wheelbase version of the Mercedes-Benz W123. Some were converted into hearses and ambulances by coachbuilders like Binz while others – including the Sheikh’s – were sold to private buyers as limousines. Don’t let the SUV-like ground clearance fool you; it shouldn’t ride higher than a regular W123 but it’s propped up by sturdy pieces of wood. Slide of Mercedes-Benz 500 SEL We told you the Sheikh likes the colors of the rainbow. Used for parades and special events, this Mercedes-Benz W126 received a multi-colored paint job in addition to a wider rear track and a pair of side exhaust pipes. Note that the interior matches the exterior; the dashboard is orange, the front seats are yellow, the rear seats are green and th
