You don’t expect to see a $143 million car waiting at a stoplight. But in Monte Carlo, that’s exactly what happened. A 1955 Mercedes-Benz 300 SLR Uhlenhaut Coupe, one of only two in the world, was spotted cruising through the streets like it was just another classic. This is the same car that set an auction record in 2022, fetching a staggering $143 million. Yet, there it was, rolling past Turn Six of the Monaco Grand Prix circuit, squeezed between an Audi and a Volkswagen van. Just last week, the Indianapolis Motor Speedway Museum auctioned a 1954 Mercedes-Benz W 196 R streamliner for $52.5 million, making it the third most expensive car ever sold. Yet even that feels like pocket change next to the Uhlenhaut Coupe.

The 300 SLR Uhlenhaut Coupe was a race car without a race, a machine designed to dominate circuits but instead became a rare artifact. Only two were ever made, and both have been locked away—until now. A recent video from Monte Carlo shows one of them on the move, rolling through the streets during a Monaco Grand Prix road closure. It’s the $143 million Uhlenhaut Coupe, a machine that once tore through Germany at speeds modern supercars would respect. Rudolf Uhlenhaut, the man behind it, once drove 144 miles (232 km) from Munich to Stuttgart in just an hour—an unthinkable feat in an era without speed cameras. This car was built for 186 mph (300 kph) sprints. Now, it was creeping through a tight hairpin at Turn Six, tucked behind a Mercedes-Benz V-Class like it belonged in traffic. A strange sight, considering it was never meant to be seen outside a race track. The video gives a rare look inside—red leather seats and a sleek silver body. The only other Uhlenhaut Coupe, still resting in the Mercedes-Benz Museum, has a blue leather interior. Both house a 3.0-liter naturally aspirated straight-eight engine, pushing 306 horsepower and 233 lb-ft of torque, paired with a five-speed manual transmission. It may not sound like much today, but the 2,200-pound (998 kg) chassis made it a rocket in its time. There’s just one problem. The video’s soundtrack drowns out the growl of the straight-eight, a sound that once echoed across racetracks. The car may have finally hit the streets, but the full experience—its raw mechanical fury—is still just out of reach. Uhlenhaut’s Daily Driver Was Faster Than Most Race Cars The Mercedes-Benz 300 SLR was supposed to tear across North America in the 1955 Carrera Panamericana, a brutal endurance race where only the fastest and toughest machines survived. But the event was canceled, and just like that, the 300 SLR never got its shot at competition. That didn’t stop Rudolf Uhlenhaut from making use of it. As the head of Mercedes-Benz’s racing program, Uhlenhaut wasn’t just an engineer—he was a driver, one fast enough to rival the professionals. With no races left to enter, he turned the 300 SLR into his company car. Read More 1957 Chevrolet Corvette SS Goes to Auction After Decades in Museum Storage He actually drove it. A lot. One day, running late for a meeting, he covered the 137-mile stretch between Munich and Stuttgart in an hour. No highways, no radar speed traps—just open roads and a car that sounded like a fighter jet at takeoff. His secretary could hear him from miles away, the scream of the side-exit exhausts announcing his arrival long before he pulled into the lot. The car was so loud that Uhlenhaut later needed hearing aids—an occupational hazard when your daily driver is a race car with no mufflers. In 2022, one of the two 300 SLR Uhlenhaut Coupes sold for $143 million, making it the most expensive car ever. That price shattered the previous record, held by a 1962 Ferrari 250 GTO, which had sold for $70 million in 2018. The new owner, a well-known UK collector, has kept their identity private.
