Among the most iconic sports cars ever constructed, the Mercedes-Benz 300 SL Roadster represents the ultimate evolution of one of the marque’s most important postwar achievements. Rooted in the competition-bred 300 SL racers of 1952, the production 300 SL quickly became a symbol of technical excellence. While the dramatic Gullwing Coupe captured the world’s imagination upon its debut at the 1954 New York International Auto Show, it was the Roadster, introduced in 1957, that refined the concept into a more sophisticated, usable, and thoroughly resolved grand touring sports car.

Constructed largely by hand and produced in limited numbers with just 1,858 examples built through 1963, the 300 SL Roadster was far more than a simple open variant of the Gullwing. Extensive re-engineering was required to transform the coupe’s tubular spaceframe into an open configuration while simultaneously improving ride quality and handling. A revised rear suspension geometry significantly tamed the swing-axle behavior of earlier cars, while Michelin X radial tires became standard. To maintain performance despite the Roadster’s added weight, Mercedes-Benz further optimized the legendary 3.0-liter inline six with a competition camshaft and available higher compression, preserving the car’s exhilarating character.

Completed in early 1959, this 300 SL Roadster was delivered new in April of that year to the Karl Kunze Company of Berlin, Germany, as documented by its original Wagenkarte. European delivery features, including kilometer-based instrumentation and amber rear lenses, confirm its early life abroad. The Roadster remained in Europe for its formative years before being imported to western Canada in the early 1970s.

At that time, the car entered the ownership of Walter Kupka, a proprietor of a repair garage specializing in fine European automobiles, an ideal early custodian for the car. In 1979, it was acquired by noted Vancouver restaurateur and longtime automotive enthusiast Bud Kanke, who preserved the car within his collection for several years. One additional Canadian owner followed before the 300 SL transitioned to the US, joining the collection of Portland hotelier Bruce Stevenson.

Subsequent ownership took the Roadster to California, where it passed through the hands of Seth Gersch of Hillsborough before being acquired by prominent Southern California collector Tony Podell. During Mr. Podell’s 13-year tenure, the car benefited from extensive mechanical attention, with numerous receipts documenting work to major systems including brakes, fuel delivery, suspension, cooling, and related components. This conscientious mechanical stewardship enabled the Roadster to be driven as intended, culminating in successful participation in two of North America’s most respected vintage driving events: the Copperstate 1000 and the Colorado Grand.

Finished in its factory correct Weissgrau (White Gray, DB 158), this Roadster presents with a timeless and elegant demeanor. The red leather interior displays an appealing, gently worn patina that speaks to careful use rather than over-restoration, enhancing the car’s authenticity and charm. While no longer retaining its originally installed engine, this 300 SL is fitted with a correct and period appropriate 3.0-liter inline six-cylinder powerplant that has been stamped with the original engine number. The Gull Wing Group registry notes the original engine for this car was replaced sometime around 1979. Chromed Rudge-style wheels lend a purposeful, competition-inspired stance, while wide lap belts reinforce its sporting character. The folding soft top stows cleanly beneath the hinged tonneau, preserving the Roadster’s graceful lines when lowered. The car is accompanied by a tool kit, as well as a desirable two-piece set of color-matched, fitted luggage.

Acquired by the current collection in 2015, the Roadster has been well cared for over the past decade, with an emphasis on continual improvement rather than static preservation. Nearly $60,000 in documented service and maintenance has been invested during this period, with work performed by leading specialists including Hjeltness Restoration, the Mercedes-Benz Classic Center, and Intrepid Motorcar. Today, the 300 SL Roadster stands as one of the most rewarding classic sports cars to own and drive, combining legendary performance with comfort, refinement, and enduring style. This example, distinguished by its sympathetic long-term stewardship, offers an exceptional opportunity to acquire a Roadster that is not only historically significant but genuinely usable.
