Introduction
This are the biggest cars in the world and it actually drives. They aren’t just build to drive. They are built to be remembered sculpted like art, crafted in secrecy and priced beyond imagination.
These machines were never meant for the masses. They were designed for the few, admired by the world, and too extraordinary to ever be repeated. So here are rarest and most expensive cars in the world that were never made again.
Here are 12 Rarest and Most expensive Cars in the world
01) Pagani Zonda HP Barchetta :

There are only three cars in the world called the Zonda HP Barchetta and each one looks like it came from another planet. Designed by Horatio Pagani Himself as a final tribute to his legendary Zonda line, the Barchetta first showed up at pebble beach in 2017.
It wore a body made entirely of deep blue exposed carbon fiber finished with a bold while racing stripe and polished silver wheels. It has no roof, barely any windshield and the rear wheels are partly covered by curved carbon fiber panels. Even thee bolts are crafted like film jewelery. But this car is not just about looks its an absolute beast.
Sitting right behind the driver is an massive. 7.3 L Mercedes AMG V12 engine. It cranks out 800 horsepower and 62% pound feet of torque. Paired with a six speed manual gearbox, the car rocket from 0 to 60 in under 3 seconds and can hit a top speed of around 221 mph. Of course, It is but that makes it aurora.
That makes it even more alive. When it launch, the barchetta was priced at around $ 17 Million, making it the most expensive new car on the market until the Roll-Royce boat trail showed up four years Later. Pagani kept the first one for himself.
The second is believed to be in a private museum owned by a collector known as Grey B and the third was delivered to Russian businessman Oleg Igor. In 2022 Ignorov’s Bartetta was involved in a serious crash during a rally in Croatia. The Damage was massive ripping off part of the rear end.
But instead of scrapping it, Pagani had it shipped back to modern, Italy. Over the next 20 months, his team restored it piece by piece, laying each carbon fiber strip by hand until the car looked brand new again. Today, the HP Barretta isn’t just rare, its priceless. A perfect specimen is now estimated to be worth over $ 20 Million.
02) 1921 Helica De Leyat :

The 1921 Helica Delayat looked like a plane that had lost its wings and sounded like on too. Built by French Aeronautical engineer, Marcel Leat. This Bizarre Machine ran on a front mounted wooden propeller, not an engine driven axle. Between 1919 and 1925.
Leat built around 30 units all with bodies made from light weight plywood and passengers sat single file inside a narrow fuselage while the spinning prop sat just inches from the driver’s face, weighing only 550 lbs, the Helica was astonishingly light.
Some version ran on a modest 8 horsepower Scorpion flat twin, while other used an 18 horsepower Harley- Davidson VI twin and yet one Helica managed to reach 106 mph at the mount by track in 1927, setting a record that stunned spectators and reportedly terrified its driver.
The design skipped almost every heavy car part you can think of. No Clutch, no differential and no transmission. Steering was done through cables pulling on the rear wheels. But the trade off were real. The open cockpit blasted, passengers with dirt and any collision up front could send the propeller straight into the drivers lap.
Still it returned an impressive 48 m per gallon, proving layout’s point that less weight and fewer moving parts could go a long way. The means of Propulsion for the future was going to be propeller not just for cars but for airplane and for buses and boats and everything.
When Leat unveiled it at the 1921 Paris motor show, excitement was high and order poured in. But with frightening safety regulation and an economic down turn very few were delivered.
Today only four Helas are known to exist one in Monaco’s Royal Car Collection, one in France’s cite De L’Automobile. One at the lam motor museum in Tennessee and one in private hands because so few survive an sales are almost non- existent, experts estimate its value at around $ 20 Million.
03) Bugatti Chiron Super Sport 300 Plus :

In August 2019, Bugatti test driveR Andy Wallace did something no one else had ever done. He pushed a lightly modified Chiron to 304.88 mph on Volkswagen’s air Allesian test track in Germany. That run made the Chiron SUP sport 300 plus the first production based car to ever break the 300m barrier To mark the record, Bugatti announced they would built just 30 units of the Super sport 300 Plus.
Every car came finished in exposed black carbon fiber accented with striking jet orange stripes. Now all 30 of the customer cars are finished in exposed black carbon fiber accented with striking jet orange stripes. Now all 30 of the customer car are finished with this bright orange livery over the piano black tinted exposed carbon fiber.
The tail was extended by nearly 10 in the help manage air flow at high speeds. Massive side intakes suck in air like jet engines and the Michelin Pilot sport cup 2 tires were so extreme they were X-rayed before installation and filled with nitrogen for added stability.
Under the hood is Bugatti signature 8L Quad-Turbo W16 Engine tuned to produced 1578 horsepower, though Bugatti rounds that to 1600. It’s an 8L Quad-Turbo W16 Engine and it puts out 1600 horsepower depending on which version of the car you have.
That’s enough power to out accelerate most small aircraft, but for safety reasons, every production car comes with an electronic limiter that caps top speed at 273 mph. When Bugatti opened the order books, each car was priced at $ 3.5 Million or around $ 3.8 Million at the time. Every unit sold out within days.
Now if one even comes up for sale, it can trade hands privately for about $ 6.4 Million to $ 7.5 Million depending on Mileage and condition. But this car is more than a number on a speedometer.
It pushed the bounaries of what a road car could be and gave new life to the legendary W16 Engine that once powered the Veyron with only 30 ever built, not follow up planned and a world record under its belt, the Chiron super sport 300 plus isn’t just rare, its untouchable.
04) Porsche 916 :

The Porsche 916 was supposed to be the car that took the modest 914 and turned it into something that could go head to head with the big names. And for a brief moment in the early 70s it looked like it would. In 1971, Porsche engineers took the lightweight 914 chassis and dropped in a 2.4 L flat 6 from the 911s, giving it about 190 horsepower.
The following year, 10 more prototypes were built. Some of them upgraded with a 2.7 L carrera engine that pushed 210 horsepower. Even the base version could hit 0 to 60 in under 7 seconds and reach 145 mph, while the hotter models got closer to 150. This wasn’t just a power upgrade. Porsche went allin.
The 916 had a reinforced chassis, widened fenders, steel roof panels and larger wheels. Inside, it came with full leather interiors and even a sunroof features you wouldn’t find in any regular 914. Porsche had big plans for this car, but the price tag killed it.It was actually quite a cheap car and it just wasn’t very fast.
Well, this is not that 914. At 40 to 50,000 Deutsche marks, around $ 13,000 t0 $ 15,000 back in 1972 or nearly $ 100,000. Today, it was more expensive than a fully loaded 911s. So Porsche cancel the project, leaving behind only 11 cars. Those 11 cars are now ultra rare collection piece.
The most famous one, chassis 0011, was delivered to Loiuse P, the sister of Ferry Porsche. After restoration, it sold in 2020 for $ 957,000. Another example, nicknamed bruthus was sold a year earlier in Paris for $ 150,000 and even an unrestored version was expected to sell for nearly $ 1 million in 2021.
Its simple only 11 were built. All of them survived and each one is completely unique in color, trim and engine setup. Some even believed the car was shelved because it out performed the 911 and Porsche didn’t want that. Today, a clean 916 can fetch over $ 1.4 Million. And if the PH car comes up again experts say the price could easily double.
05) Ferrari 250 G7 Spyder Convertible :

The Ferrari 250 G7 California sypder wasn’t built for the masses. It was built for movie stars. Racer’s and the boldest Ferrari fans on the planet. It all started in the late 1950s when US dealer Luigi Chinetti asked Ferrari for something special. A convertible that could turn heads in Baverly Hills and tear up a racetrack the next day.
Ferrari delivered between 1957 and 1963, Just 106 were made that included 50 long wheel base version and 56 short wheel base cars all wrapped in ultra light skagglete coach work hammered by hand. Under the hood sat a 3L V12 designed by the legendary Joakino columbbo.
It made around 280 Horsepower pushing the spider to more than 145 mph and from 0 to 60 in just about 7 seconds which back then was flatout astonishing. Add four-wheel disc braker and a race ready suspension and you had a car that didn’t just look fast, it was fast.
In fact, factory backed spider took class wins at Sebring in both 1959 and 1960. Then came the legends who owned them in 2008, a dark blue SWB that once belonged to actor James Coburn sold for just over $ 10.9 Million. A barn find that belonged to French film star Alan Dong sold in 2015 for a record breaking 18.5 Million.
And in 2023, the very first SWB Spyder ever made, Chassis 1795 G7 sold for 17.05 Million dollar at Mterrey. But the car’s fame doesn’t stop with collectors. A replica starred in Ferris Buer’s day off, making it a pop culture icon is putting his up for sale hoping for a price near $ 14 Million.
06) Gibbs Aquada :

Imagine, you are speeding down the highway at 100 mph when suddenly you hit the water. But instead of stopping your car tucks in its wheels, kicks up a jet pump and 12 seconds later, you are gliding across the surface at 31 mph that’s not a dream. That’s the Gibbs Equator, the world’s first real high speed amphibious car, unveiled in London back in 2003.
This isn’t some backyard project. The Aquadada holds over 60 patents. Its got retractable wheels, a self leveling suspension and a Marine grade jet propulsion system that handles both roads and waves with ease.
At the center is a 2.5 Liter Rover V6 Engine pushing out 175 horsepower to the rear wheels. It hits 60 in about 8 1/2 seconds with the driver sitting in the middle just like in a McLaren withh two seats flanking each side. It has no doors, not to look cool, but to keep it fully watertight. And this thing isn’t just about engineering flax.
It is an exciting product and we are very fortunate in Auburn hills to have them locate there. In June 2004, sir Richard Branson used the Aquada to cross the english channel.
He blasted from Dover to Calala in 1 hour 40 Minutes and 6 seconds, slashing the old Amphibious vehicle record by over 4 hours. British enterprenuer Richard Branson set a strange new world record.
He drove across the English Channel. A few weeks later, a top gear Journalist drove the grand Prix from the water, but even with its jaw dropping performance the Aquada was just too far ahead of its time.
Each one cost over $ 150,000 about a 4 million and Navigating the red tape for something that was both a car and a boat was a nightmare. Fewer than 50 were ever built. Today a clean unit can go for over $ 250,000 Gibbs eventually pivoted to licensing its tech for military and leisure use, but the original Aquada remains untouchable.
07) Lamborghini Egoista :

The Lamborghini Egoista which literally means selfish in Italian isn’t just rare, its one of one. This is the most powerful Lamborghini ever made built in 2013 to mark Lamborghini’s 50th Anniversary it was never meant to be shared. Designer Walter Dilva called it a car for one person only and he meant it.
The body is shaped like a raging bull mid charge finished in matte Gray with sharp orange Panels that actually shift at speed to control air flow. Under that wild exterior, it packs the 5.2 L V10 from the Lamborghini Gallardo Reworked to deliver about 600 horsepower.
That’s enough to launch this carbon fiber spaceship from 0-60 in around 2.4 second with a top speed of 217 mph. And the cockpit, its not a car interior. Its straight from a fighter jet. You get a removable steering wheel, a full head up display, and a racing harness like a Pilot’s Ejection seat. Ever getting out of the car is an event.
You pop the Canopy, stand up on the seat and climb out over the side like you are existing an F16. The lights on the outside follow aviation rules too with red, green and white indicator. The wheels and lower panels are even coated in radar absorbing material the same stuff used on stealth aircraft.
Lamborghini only built one Egoista for a whole decade, they kept it tucked safely inside their museum in Santagata Bolognesei saying it would never be sold. Hybrid Lamborghini, the car that was when they actually debuted these Y lights. But in early 2025, reports emerged that it had quietly been sold to a swiss collector for a jaw dropping $ 117 Million.
Lamborghini hasn’t officially confirmed it, but multiple sources say the figure makes sense for a fully functional one-off concept with this much hype. And if that sale price is real it proves one thing, some people really with pay anything to ride alone at the top.
08) Mercedes-Benz 300 SLR Unlehnant conpe :

In may 2022, the world of classic cars changed forever, behind closed doors a 1955 Mercedes Benz 300 SLR unlehnant coupe was sold at auction for a jaw dropping $ 135 Million. That’s about $ 142 Million.
No other car in history has ever sold for that much. Not even close. Only two of these cars were over built. They were created for the 1956 racing seasons, but mercedes pulled out of motor sports after the tragic Lemore disaster the year before back in 1955, he was going top speed all the way from Frankfurt to Munich in this.
One of the cars was kept by Rudolph Ulenhout Mercedes lead Engineer, as his personal ride, which is why the car now carries his name. The body is made of hand shaped magnesium and underneath is a lightweight space frame chassis weighing just over 2,200 Lb. Its powered by a 3 L straight 8 Engine pushing out 302 horsepower.
This had more horsepower this engine right here than what they were using in the F1 cars back then. That was wild for the 1950s. It could hit over 186 mph. A 5 speed gearbox sits at the rear, giving it incredible balance. Test driven said it sounded like a fighter jet at full Throttle and it wasn’t just for show.
In 1956, Ulenha drove from Stutgart to Munich about 137 mile in just 1 hour. That’s means he averaged more than 130 mph. On public roads every time this car appear at an event, Mercedes had to send a trained technician just to take the engine apart and reassemble it for display.
That’s how complex and rare it is until the auction, both cars stayed with Mercedes. The second one still lives in their classical collection in Stuttgart. The money from the record breaking sale now funds the Mercedes Benz fund, supporting scholorship in STEM and sustainability.
09) Aston Martin Valkyrie :

The Aston is what happens when you let a formula 1 genius design a road car. Created in Partnership with Adrien , Red bull’s top F1 engineer, this hyper car takes racing tech straight to the street and 40 AMR pro trackly versions were built. Such an a fantastic opportunity to just be able to go absolutely mad with an amazing piece of engineering history.
Each buyer had to sign an agreement not to resell it for profit or risk being banned from future. Aston Martin special edition. Under the hood, or rather behind the driver sits a 6.5 L cosworth V1 12 That revs past 11,000 RPM. Its paired with a hybrid battery system that together unleashes 1,155 horsepower.
That’s enough to launch the lightweight carbon fiber body past 217 mph. Even with all that speed, its still street legal. Thanks to hidden ground effects tunnels underneath the car. These keep it glued to the road without needing giant wings.
This car is so extreme, even the stories around it are wild. One prototype lapped the silverstone circuit so fast that the sensors had to be recalibrated. And starting next year the Valkyrie will compete at Lamar and Qatar as part of Aston Martin’s returns to top tier endurance racing. Their first serious shot since 1959.
The price around $ 3.5 Million but even before the final design was ready. Buyer were reserving slots using virtual reality. The cabin is so tight you practically wear it.
The steering wheels doubles as a key, and the downforce is so strong you could hold a pickup truck upside down on the roof at full speed with production ending in 2024. Resale prices are already climbing. One law Mileage example in Europe was recently listed for over $ 3.4 Million.
10) Rolls -Royce First Model :

In 1904, Charles Rolls and Henry Royce teamed up to build their very first car, the rolls Royce 15 Horsepower. Only 6 of these handbuilt machines ever rolled out of the workshop, and today just one remain. It carefully preserved by the royal Scottish Automobile club in Abedinia.
And its one of the rarest piece of Automobile history still in existence under the hood sits a 3 L, 3 Cylinder engine that produces, just like the name says 15 horsepower. When the car was then disassembled at the end of it, the cost of rectifying worn parts was minimal.
That might sound like nothing today. But back in 1904, it was enough to move this light weight car at speed of up to 40 mph. And at a time when most roads were unpaved and bumpy that was seriously fast. But the magic of this car wasn’t just its speed it was Henry Royce’s clever engineering.
He used a long stroke engine for smooth torque and added a transmission brake behind the gearbox so the driver didn’t have to rely on the fragile drum brakes. The artillery style wooden wheels were built tough and a unique governor kept the engine running steady.
The features made the car surprisingly smooth and reliable for its time. Inside, it felt less like a car and more like a private lounge. It had wide coach doors and deep leather seats, a clear sign of the luxury rolls- Royce would soon be known for every panel was hand riveted making each unit incredibly expensive to produce. That’s why only 6 were ever built. That last surviving example is now valued at over $ 35 Million.
11) Stout Scarab :

In 1935, William Bushnell stout built something so far ahead of its time that most people didn’t know what to make of it. The Stout Scarab with its smooth teardrop shape and futuristic body, it looked nothing like the Boxy cars of that era. And this is one of the creation. Fewer than a dozens were built.
But it wasn’t just about looks. Stout moved the 85 horsepower Ford flathead V8 engine to the back, which gave the interior a wide, flat floor an enough room for swivel seats and a foldout table. It wasn’t a car. It was a rolling living room. The design was packed with features no one had seen before.
It had no running boards, hidden door hinges and a sloped wind shield that helped it cut through the air. The Scarab also used a unibody chassis which was incredibly rare back then supported by independent coil spring suspension, it was so smooth and quiet on the road the Stout called it a land Yacht.
This is much nicer than most cars in the 30s. They had even with the engine in the back,it could cruise at 80 mph which was fast for a time when most roads were still gravel or dirt.
But all that innovation came at a cost. Each Scarab was hand built and cost around $ 5000, more than 4 times the price of a luxury Lincoln Zephyr stout hoped to produced 100 a year, but in the end only 9 were made and today just 5 are known to survive was just trying to design a better car.
He wanted more room and its no bigger than a chevy or a ford of that era, but it has twice the interior space. One is at the Detroit historical museum. Another spent years in the owls head transportation museum in Maine and one is tucked away in a private collection only seen at elite car shows.
Stout came from the aviation world and it showed every part was drilled and lightened like an airplane. There was no drive shaft tunnel, so the floor stayed completely flat. The luggage went in the front. Today, expert call the scarab the first true minivan,a full 50 years before Chrysler made it mainstream spotting one today is incredibly rare, but is DNA lives on in every family van on the road.
12) 944 Oldsmobile F-88 :

The 944 oldsmobile F88 looked like it had rolled straight out of a sci-fi comic and onto the showroom floor. Designed by Harley Earl, general motors legendary stylist this two seater concept car was built on the same 2-in wheelbase as the corvette but packed a very different punch.
Under the hood satsmobile own 324 cubic inch rocket V8 paired with a four speed hydroactic transmission. It produced around 250 horsepower which was serious power at a time when most cars struggled to hit 100 mph.
The body was all about drama. It used fiberglass panels to keep weight down, a curved plexiglass windshield and a dashboard fined with gold bullet Gauges. A designer so striking it later inspired the first oldsmobile cutless interiors.
GM unveiled car driving its traveling motorama show, promoting it as the future of American performance and designed, but the dream was short lived only four prototypes were ever built and most were later destroyed by GMs legal team. According to legends, one car escaped destruction by being quietly packed into wooden crates marked as scrape metal.
That surviving car finally resurfaced in 2005 at a Barrett Jackson auction in Scottsdale. Bidding was intense and the car sold for $ 3.24 Million, setting a record for an American concept car.
The buyer was John Hendris founder of discovery channel. He put the car on permanent display at his gateway Canyon’s automobile museum in colorado weighing just over 2600 lb, the F88 was capable of reaching over 140 mph a number no production oldsmobile would touch for decades. But speed isn’t what makes it legendary.
This car captured a moment when detroit wasn’t just building cars. It was building dreams. Today its estimated to be worth over $ 4 million, but in truth its priceless.
