Forty-two vehicles spanning 140 years of history, and Mercedes-Benz itself only owns four of them. That’s the quiet stunner behind “World-Class: 100 Years of Mercedes-Benz,” the new exhibit opening May 23 at the Petersen Automotive Museum in Los Angeles.
The rest come from private collectors and deep-pocketed enthusiasts, including the Keller Collection, which accounts for roughly a quarter of the cars on display. During an opening night panel, a Mercedes-Benz Classic Center representative admitted there are cars in this exhibit the company would kill to own. That’s not boilerplate humility. It’s a confession about where the really important metal actually lives.
Museum curator Shervin Nakhjavani started assembling the show when he joined the Petersen in August 2024, with a specific mission: remind Americans that Mercedes-Benz isn’t just the leased C-Class in their neighbor’s driveway. The brand traces back to Carl Benz’s 1886 Patent-Motorwagen, though the Daimler-Benz merger that created the company as we know it didn’t happen until 1926. That makes this a clean centennial.
The exhibit fills the Petersen’s largest ground-floor hall, and the highlights are stacked deep. A 1936 540K Cabriolet by Erdmann & Rossi, built to heiress Barbara Hutton’s exact specifications, commands center stage. She demanded visual symmetry, so the car got fake exhaust pipes on the left side of the hood.
Nearby sits a 1938 540K Stromlinienwagen streamliner capable of 100-plus mph, originally developed for a Berlin-Rome race that never happened. It ended up as a Dunlop tire mule. Even prototype supercars have unglamorous second acts.
The real brain-scrambler is the 1953 300SL “Hobel” prototype, nicknamed after the German word for “slicer.” Mercedes planned to build ten as successors to its W194 race car. They built exactly one, then pivoted to Formula 1.
The Hobel looks like a 300SL Gullwing filtered through French and British design sensibilities — funkier, weirder, with gill vents that the production car politely deleted. The Petersen smartly parked a 1954 300SL development prototype right next to it for comparison.
Celebrity provenance makes cameos without dominating the show. Walt Disney’s red 1964 Pagoda SL, still family-owned, sits alongside Clark Gable’s custom-ordered 1956 300Sc Cabriolet. A six-door 1971 600 Pullman Landaulet, one of 59 built, once belonged to one of Senegal’s wealthiest men.
The performance wall reads like a fever dream: a white 1984 500SEC 5.4 AMG widebody, the sole W124 Hammer wagon ever made, a CLK DTM coupe, a 190E Evolution II with the best fender flares in the building, and a CLK GTR Roadster. A 1989 Sauber C9 and a 2005 McLaren-Mercedes MP4-20 F1 show car handle the racing duties alongside a 1938 W154 that won its debut at the Nürburgring. That car was piloted by Dick Seaman, who unfortunately commemorated the victory with a Hitler salute.
The sleeper star might be the 1991 C112 supercar concept. Active suspension, automatic rear spoiler, advanced aero, and an interior that embarrassed contemporary exotics. Mercedes took nearly 700 orders before killing the project.
The car has existed primarily in press photos and collector lore for three decades. Its physical presence here is genuinely startling.
Before visitors even reach the main hall, a Unimog flatbed and two cars — a 1966 250SE coupe and a 1981 240D sedan — greet them in the lobby. Both sedans have covered more than 1.3 million miles each. That’s the kind of quiet flex no other automaker can replicate.
The exhibit runs through April 25, 2027, with cars expected to rotate in and out. For anyone who thinks they’ve seen everything Mercedes has ever built, the Petersen is betting otherwise. Based on what’s on that floor, the Petersen wins that bet.
