When Mercedes-Benz concluded the production of the celebrated 300 SL Gullwing in 1957, they didn’t just rest on their laurels. Instead, they unveiled its breathtaking successor – the 300 SL Roadster. This convertible marvel continued the legacy of its predecessor while carving out its own distinct identity as a sophisticated and powerful grand tourer. Produced until 1963, the Roadster was not merely a Gullwing with a soft top; it was a significant evolution, meticulously engineered to enhance both driving dynamics and passenger comfort.
The transformation from Gullwing to Roadster involved substantial modifications to the lightweight, welded steel chassis. Engineers redesigned it to accommodate conventional doors with roll-down windows, a feature immediately enhancing practicality and ease of access. Furthermore, a newly developed rear axle was incorporated, specifically aimed at improving ride comfort and mitigating the Gullwing’s tendency towards oversteer. These mechanical refinements underscored Mercedes-Benz’s commitment to creating a more refined driving experience.
Beyond the engineering enhancements, the 300 SL Roadster received visual updates that amplified its glamorous appeal. Revised head and taillights brought a fresh, modern touch to its styling. A smaller fuel tank was strategically implemented to liberate space for a more generous boot, making it more suitable for grand touring. Crucially, the Roadster retained the potent 218 PS output from its engine, ensuring it delivered exhilarating performance to match its stunning aesthetics. These combined improvements firmly established the Roadster as a consummate sporting grand tourer, perfectly blending luxury, performance, and open-top exhilaration.
Historical records reveal that during its inaugural year of production in 1957, 554 units of the Roadster were completed. Among these early examples is a North American specification model, originating from late 1957, which serves as a compelling illustration of the Roadster’s early appeal. Detailed in a copy of its original delivery card, chassis number 198.042.7500672 was originally finished in an elegant Graphite Grey exterior, complemented by a luxurious Cream leather interior – optional upgrades selected at the time of order. Further enhancing its specification for the American market, a Becker Mexico radio and stylish whitewall tires were also specified. The car’s journey to the United States culminated on November 25, 1958.
According to the meticulous research compiled in Eric Le Moine’s esteemed 300 SL registry, chassis 198.042.7500672 found its first owner on the West Coast of the United States, Mr. Tom McBurney of Santa Barbara, California. Embracing the quintessential California lifestyle, this Roadster remained a fixture along the state’s picturesque coastline. In 1974, it transitioned into the ownership of financier Mr. Alfred T Moret in Carlsbad, further cementing its Californian provenance. Later, in 1986, The Aumann Collection acquired this significant example and repatriated it to Germany, adding it to their distinguished collection of classic automobiles.
While now sporting a rich dark green leather interior from a subsequent reupholstering, this particular Mercedes-Benz 300 SL Roadster retains its original, matching-numbers components, including the body, chassis, and the powerful 3-litre straight-six engine. It is noted that the front chassis crossmember appears to have been replaced at some point in its history, but all other numbers corroborate its authenticity. Accompanied by a comprehensive history file, this 300 SL Roadster presents a unique opportunity. A discerning new owner could choose to return it to its factory-correct Graphite Grey and Cream color scheme, meticulously restoring it to its original glory. Alternatively, appreciating its current presentation, it is perfectly poised to be enjoyed immediately, offering the quintessential open-top driving experience that only a Mercedes-Benz 300 SL Roadster can deliver.
