Abounding in aesthetic beauty, powerful competition-bred specifications, and superior build quality, the Mercedes-Benz 300 SL Roadster is one of those rare paragons of automotive excellence that attest to the brilliant engineering of post-war Germany. When the Roadster was introduced in 1957, the new model addressed many of the perceived shortcomings of the outgoing 300 SL Gullwing, which was more closely tied to the 300 SL racecar of the early 1950s—primarily, redesigning the Gullwing coupe’s tube frame allowed for the use of conventional doors, which improved the ease of ingress and egress. This refinement also allowed for the implementation of standard wind-up windows, which significantly improved interior airflow and commensurate cabin comfort.

The unforgiving high-pivot swing-axle geometry of the Gullwing coupe, which was adapted from the W186 chassis of the larger 300 sedans, was discarded in favor of a low-pivot swing-axle rear suspension borrowed from the later 220A sedans. This configuration utilized a coil spring mounted transversely above the differential that was linked to the axles by vertical struts, which served to minimize oversteer. The frame and suspension redesign also allowed for the installation of softer coil springs, which provided the Roadster with a more comfortable ride quality without affecting the sporty handling. Furthermore, a smaller gas tank and longer rear overhang facilitated the enlargement of the trunk space, a dividend for owners interested in extended touring.

The highly developed inline-six-cylinder engine was now standard-equipped with the sport camshaft that had been so effective in the racing alloy-bodied Gullwing, increasing output by 25 horsepower. While a 3.64:1 rear axle ratio was a standard feature of cars specified for the United States, a lower 3.89:1 ratio was available, improving acceleration. In 1961 four-wheel disc brakes became standard equipment, improving the 300 SL’s stopping capabilities, and bringing the model in line with concurrent mechanical advancements at Ferrari.

Easier to drive and more comfortable to use, the Roadster is largely regarded as an improvement over the Gullwing in every practical consideration, and it is still highly regarded by collectors today. When production concluded in 1963, just 1,858 cars had been built, and surviving examples now serve as the centerpiece of numerous marque collections.

The magnificent Mercedes-Benz 300 SL roadster featured here is finished in gorgeous factory-correct Fire Engine Red over a tan leather interior and matching folding convertible top. This exquisite 300 SL roadster was manufactured at this Stuttgart-based Mercedes-Benz works completed on December 27, 1957, as a 1958 model year car that was equipped for the North American market and dispatched to Los Angeles, California where it was delivered to its new owner, Mr. Charles B Kendall Jr of Pasadena California. After many years of meticulous ownership, Mr. Kendall sold it to the famed journalist, television commentator, and legendary champion sports car racing driver Bob Atkin. Mr. Atkin then would sell to its third and final owner, noted collector Mr. Arnold E Petsche of Arlington, Texas where it remained for 36 years until our acquisition. Under Mr. Petsche’s ownership a restoration was commissioned by famed Pebble Beach winning restorer Paul Russell and beautifully maintained since completion, and still presents beautifully today! We are extremely proud to offer this investment-grade Mercedes-Benz 300 SL roadster to the most demanding collector, investor, or enthusiast who desires to acquire an exceptional, beautifully restored fully documented example with impeccable provenance!
