Using a separate tubular cruciform chassis, the 300 boasted independent coil spring suspension all round, together with supplementary torsion bars at the rear and servo-assisted drum brakes, while transmission was a four-speed manual with column change. Power came from a 2996cc, straight six cylinder engine which, via a single overhead camshaft and twin Solex carburetors, produced 100 bhp – sufficient to propel the big four-door limousine, which weighed some 4,000 1bs, to a 98 mph top speed and 0-60 mph in 16 seconds.
During the ’50s the engine underwent various improvements through constant development, power rising first to 115 bhp for 1953 and then to 135 bhp for the later 300B and 300C models, the latter also featuring new rear suspension with swinging half axles, a larger rear window and the option of automatic transmission for the first time. By the time the final 300D model appeared in 1956 it had Bosch fuel injection, similar to that used on the sensational 300SL sports car. Production of all 300 models ceased in 1962.
Finished in Mercedes Silver, this 300S Cabriolet A, the S denoting a more luxurious interior than standard, has come from the private collection of former Swiss Olympic ice hockey competitor, Hans Durst. Fastidiously maintained, and with a believed genuine mileage of just 36,560 miles, this stylish and majestic motor car benefits from a recent engine rebuild by Swiss specialists.
