Mercedes-Benz 300 SL Roadster

The Mercedes-Benz 300 SL Roadster (W198 II) succeeded the legendary Gullwing coupe in 1957 and, in many ways, surpassed it. While the Gullwing captures the imagination with its dramatic doors, the Roadster was the superior automobile: it handled better, was more practical, and offered an equally thrilling driving experience with the added pleasure of open-air motoring.

The Roadster retained the Gullwing's 3.0-liter fuel-injected inline-six engine, but in a revised chassis that addressed the original car's shortcomings. The most significant change was to the rear suspension: the Gullwing's low-pivot swing axle, which could cause dramatic oversteer in the hands of the unwary, was replaced with a compensating single-pivot swing axle with a lower roll center. This made the Roadster significantly more predictable and safer at the limit.

The engine, Mercedes-Benz's landmark mechanical direct fuel injection system developed with Bosch, produced 215 hp in standard form -- slightly more than the Gullwing's 215 hp, thanks to a revised camshaft and improved intake manifold. A Sport camshaft option raised output to 235 hp for competition use. The fuel injection system was the first of its kind in a production car and represented a quantum leap in engine technology.

With the tubular space frame modified to accommodate conventional doors (rather than the Gullwing's top-hinged units), the Roadster offered much easier ingress and egress. A removable hardtop was available for all-weather use. The interior was trimmed in leather and featured comprehensive instrumentation, reflecting the 300 SL's dual nature as both a high-performance sports car and a luxury grand tourer.

The Roadster proved more popular than the Gullwing, with 1,858 examples produced over its seven-year run compared to 1,400 Gullwings. This reflected the Roadster's greater practicality and improved dynamics, which broadened its appeal beyond hardcore sports car enthusiasts to include the broader luxury market.

Notable owners of the 300 SL Roadster included celebrities, royalty, and racing drivers of the era. The car was a fixture at the most glamorous events of the late 1950s and early 1960s, from the Cannes Film Festival to Palm Beach society events.

In 1961, Mercedes-Benz updated the Roadster with disc brakes on all four wheels, replacing the original drum brakes. Later cars also received an aluminum engine block, reducing weight. These 'disc brake' Roadsters are considered the most desirable specification and command the highest prices.

Today, the 300 SL Roadster is one of the most valuable classic cars in the world. While not quite reaching the astronomical prices of the Gullwing coupe, fine Roadsters consistently sell for $1 million to $2 million, with exceptional provenance or competition-history cars exceeding those figures. The combination of Mercedes-Benz engineering excellence, timeless design, and historical significance ensures that the 300 SL Roadster will remain at the pinnacle of the collector car market.
