This 1952 Mercedes-Benz 300 S is one of fewer than 150 roadsters built during three years of the variant’s production. Refurbished in 2010, the car retains its factory color combination of White Grey over Green Grey leather and is powered by a numbers-matching 3.0L M188 inline-six with triple Solex carburetors. Additional equipment includes a column-shifted four-speed manual transmission, four-wheel independent suspension, finned hydraulic drum brakes, a dark green convertible top, a Becker Nürburg radio, a Hirschmann antenna, and a two-piece set of factory fitted luggage. Following the selling dealer’s acquisition in 2020, a mechanical freshening was performed by marque specialist Pierre Hedary and included a rebuild of the carburetors, repairs to the ignition system, and a valve adjustment. The 300 S was introduced at the Paris Motor Show in October 1951 as a hand-built sporting version of the four-door 300 series. It entered production the following summer in three configurations including a coupe, a cabriolet, and a roadster, the latter of which featured a lighter, fully retractable soft top without the cabriolet’s coach bars. Body-color 15” wheels wear chrome beauty rings and covers and are mounted with Firestone FR380 whitewall tires. Braking is handled by finned drums all around. The four-wheel independent suspension features coil springs and telescopic shock absorbers at each corner. Factory rear load-leveling adjustment is controlled via a switch under the dash. The cabin is trimmed in Green Grey leather (1070) with dark green piping over the reclinable front seats, fold-down rear bench seat, door panels, side panels, and top boot. Similarly toned carpets line the floors and trunk compartment, while bird’s eye wood accents the dashboard, door caps, and windshield frame. Additional features include an ivory-colored steering wheel with a chrome horn ring, an ivory-colored shift knob, roll-up windows, and a Becker Nürburg push-button radio. VDO instrumentation includes a 200-km/h speedometer, a rectangular clock, and gauges monitoring oil pressure, coolant temperature, fuel level, and amperage. The five-digit odometer shows 20k kilometers (~12k miles). True mileage is unknown. The 3.0-liter SOHC M188 inline-six utilizes an aluminum cylinder head that mates to the block at a 30° diagonal to allow increased valve sizes. The engine features triple downdraft Solex carburetors and a 7.8:1 compression ratio for a factory-rated output of 150 horsepower. Power is sent to the rear wheels via a four-speed manual transmission with synchromesh on all forward gears.
