The 10 Rarest Cars In The World Almost Don’t Look Real

There comes a point when the lifestyles of the rich and famous become almost unrecognizable to us normal folk. Houses begin to look like castles, meals begin to look like feasts, and even cars begin to look a little too… alien.

The 10 rarest and most expensive cars ever sold may look like they’re from another planet, but these unique vehicles are anything but extraterrestrial. The bank accounts of those who paid for them, however, must have truly been out of this world…

1. Aston Martin DBR1: Built in 1956, the DBR1 is arguably Aston Martin’s most valuable and sought-after vehicle to date. The prestigious automobile company only produced five editions of the DBR1, with the DBR1/1 selling for $22.5 million in 2017, a record for a British-made car.

But perhaps the biggest reason for the DBR1/1’s record-breaking price tag is its racing pedigree. Not only does the DBR1/1 hold claim to Aston Martin’s single victory at the 24 Hours of Le Mans (’59), but it’s also one of only three vehicles to win both the World Sportscar Championship and Le Mans in the same year.

2. Icona Vulcano Titanium: If a twenty-million-dollar piece of racing history isn’t your thing, how about a sports car made entirely of titanium? Icona’s Vulcano Titanium is a work of art in and of itself, with each vehicle requiring over 10,000 man hours to complete.


Considering that titanium is incredibly difficult to work with, it’s no surprise this top-of-the-line vehicle is one of the most expensive on the market. But for a cool $2.78 million, you can make all of your slightly less-wealthy friends jealous with a sports car that looks like it was designed by Iron Man himself.


3. Hélica de Leyat: Yes, that’s right: this is a car. Invented in 1921, the Hélica – also called “the plane without wings” – is a revolutionary vehicle created by French automobile designer Marcel Leyat. Like the aircrafts of the day, this unique machine was powered by a front-mounted propeller and was steered from the rear.


Unfortunately for Leyat, the popularity of the Hélica never really took off, and he sold just 30 vehicles between 1919 and 1925. While all known models of the Hélica are currently held by private collectors, the estimated value of the vehicle at auction is $20 million.

4. Ferrari 250 GTO: Another luxury GT built with a need for speed, the Ferrari 250 GTO was one of the most dominant sports racing cars of the 1960s. Though Ferrari racers were initially hesitant to drive the 250 GTO, the vehicle went on to pick up three World Sportscar Championships between 1962 and 1964 as well as two Tour de France cups in 1963 and 1964.

This pedigree, combined with the vehicle’s complete embodiment of the Ferrari brand, has made the 250 GTO the most valuable car in the world. Originally sold for $18,000 upon its introduction in 1962, a June 2018 auction saw a 1964 250 GTO sell for an all-time auction record of $70 million.


5. 1904 Rolls-Royce 15 hp: Born from an agreement made on December 23, 1904, between Charles Royce and Henry Rolls, the 15 hp was one of four cars produced by what would later become the Rolls-Royce company. The vehicle was sold exclusively by Rolls’ motor dealership – C.S. Rolls & Co. – for £500.

Because each cylinder of the 15 hp’s engine had to be cast separately due to the incompatibility of some of Rolls’ and Royce’s designs, only six vehicles were produced. Only one car – registered SD 661 – is known to have survived, and its value currently sits at $35 million.

6. Porsche 917 K: A vehicle that looks more like a spaceship than anything else, the 917 K singlehandedly put Porsche on the racing map. After years of coming up short, this sleek sports car placed first overall at the 24 Hours of Le Mans in ’71 and ’72, paving the way for Porsche’s record 19 outright wins in the race.

This Porsche 917 K in particular fetched a hefty price at auction, but not for the reason you might think. The 1971 film Le Mans showed this vehicle being driven by legendary actor Steve McQueen. In 2017, the car sold for an impressive $14 million, a record price for a Porsche.

7. Bugatti Type 41: Also known as the Royale, the Type 41 was marketed as the most luxurious car ever, with Ettore Bugatti planning to produce only 25 units from 1927 to 1933. Unfortunately, luxury cars weren’t very popular during the Great Depression, and Bugatti only sold three of the seven made.


The original cars still exist today, though one was destroyed by Ettore Bugatti himself after he wrecked it in an accident in 1931. The Kellner Coupe make of the Type 41 sold for $9.8 million in 1987, which would be equal to just around $21 million today.

8. Ferrari 250 Testa Rossa: The dominance of the 250 Testa Rossa cannot be understated, as this Ferrari brought home ten world championships in a matter of three years: the 24 Hours of Le Mans in ’58, ’60, and ’61; the 12 Hours of Sebring in ’58, ’59, and ’61; the Targa Florio in ’58; the 1000 Km Buenos Aires in ’58 and ’60; and the Pescara 4 Hours in ’61.

Because of its racing success, historical influence, and low production number (only 33 were made), the 250 Testa Rossa is considered one of the most valuable vintage Ferraris ever made, second only to the 250 GTO. In 2014, a 250 TR sold privately for $38.9 million.

9. Maybach Exelero: A true one-of-a-kind vehicle, the Exelero was designed as a one-off by Fulda – a German subsidiary of Goodyear – to test the range of their Carat Exelero tires. The car was designed to reach speeds in excess of 217 mph so that the physical limits of the tires could be tested.

In 2011, British motoring magazine Top Gear reported the Exelero had been sold to rapper/producer Bryan Williams – known as “Birdman” – for $8 million. Known for his extensive collection of luxury vehicles, it comes as no surprise the music icon snatched up this unique ride.

10. Aston Martin DB4 GT Zagato: The 1960 Zagato was designed to be an upgrade over the original DB4 GT, having been lightened and improved by Ercole Spada at the Zagato factory in Italy. The factory had initially planned to produce 25 cars, but low demand caused production to cease at the 20th unit.

While not as successful as Aston Martin’s DBR1, the Zagato was still a threat on the racetrack, defeating a Jaguar E Type in a 1961 British Grand Prix Support race for its first and only win. In 1962, a DB4 GT Zagato sold in New York for $14.3 million, equal to around $14.7 million today.

Since Henry Ford first rolled out the Model T, people have modified cars in just about every way imaginable. While some folks like simple upgrades that make their vehicles more efficient, others prefer flashier improvements.

When friends Duncan Forster and Phil Weicker were enrolled in college at McMaster University in Ontario, Canada, they had an outrageous idea. It mostly involved a few absurd modifications to their 1982 Chevy Malibu.

The plan? Transform the Malibu into a fully operational hot tub while keeping the car’s driving capabilities intact. With the help of a fellow student, they went to work—and saw mixed results.

“This thing was hideous,” Duncan said. “The car barely ran, but we were really proud of it.” But the middling success only made Duncan and Phil hungry for a project that would really make their friends envious.

Twelve years later, when Duncan and Phil lived in Los Angeles, they revisited their plan for a hot tub car. This time would be different, though. For starters, they were going to use a 1969 Cadillac DeVille as the body—and the end result would be street-compatible.

But first, the duo had a daunting task ahead of them. Could they overcome the mistakes they made with their last hot tub car? With a few years to evaluate where they’d gone wrong, Duncan and Phil were certainly going to try.

Project Carpool DeVille, as the duo called their efforts, required a full-body makeover of the vintage car. To start, they gutted the interior and ripping out the seats and the dashboard. After all, they couldn’t just put the tub in the trunk!

Of course, the hot tub would be heavy, especially once Duncan and Phil filled it up with water. That meant they had to reinforce the car’s steel frame and install a top-end shock-absorbing suspension system. Now it was time for the tub…

To ensure the hot tub fit perfectly in the hollowed-out DeVille, Duncan and Phil created a mold of the car’s interior (with a little help from fiberboard). Using gel and fiberglass, they covered the mold and crafted the tub. Now, how would they heat the water?

Therein lied a piece of the car’s genius—heat from the car’s engine warmed the water to about 102 degrees Fahrenheit! Other work on the engine, including an alternator upgrade, allowed the car to generate all the power it needed.

As Duncan and Phil learned the last time they attempted a hot tub car, however, the devil was in the details. After a new paint job, they sealed up the tub tight and installed a customized dashboard—with some cool perks.

Duncan and Phil added a custom throttle that controlled a manual transmission, while buttons, knobs, and switches installed above the water line allowed the hot tub’s operator to control the suspension and lights. Last but not least…

The trunk concealed all the pumps, filters, and hot tub-related gizmos, such as an overflow tank that cycled water back into the tub. While the car wasn’t exactly great for grocery runs, it operated beautifully—and that gave Duncan and Phil another idea.

“We spent six years creating the perfect marriage between two American pastimes,” Phil said. “Driving and hot tubbing.” With the design a pleasing success, the duo wasn’t content to let this thing just be a novelty item…

Naturally, Duncan and Phil figured, why not go for a world record? Pushed toward the idea by the Southern California Timing Association, the duo aimed to set a Land Speed Record for the “World’s Fastest Hot Tub.” However, they quickly hit a snag.

Racing was expensive, and if they were going to get the Carpool DeVille to the Bonneville Salt Flats in Utah—where the record would have to be attempted—they needed financial assistance. Duncan and Phil turned to Kickstarter.

Impressively with the help of 205 backers, Duncan and Phil raised $11,251—$1,251 over their goal—and secured the trailers, fuel, and other equipment they needed for the trip. In August 2014, they made it to Utah… and were immediately halted.

“For the first time in decades,” Duncan said, “the time trial event was canceled on account of there being water on the course. Not ours, but the irony wasn’t lost on us.” But after coming so far, Duncan and Phil weren’t about to quit.

The duo found a long patch of flat ground and, with cameras rolling and smartphones collecting data, they made an unofficial attempt at the record for the World’s Fastest Hot Tub.

The results? “We were limited by course length and conditions,” Phil said, but somehow, the Carpool DeVille “achieved a top speed of 50 miles per hour!” That was—though unofficial—the world record!

They wanted to make an official attempt at the record, but until they could make it back to Utah, the car served as a way to entertain and make others smile. “You haven’t really lived until you’ve sat in a hot tub and watched the world roll by,” Duncan joked.
