1957 Mercedes-Benz 300Sc “Einspritzmotor” Roadster Listed on BaT

Bring a Trailer reports a 1957 Mercedes-Benz 300Sc “Einspritzmotor” Roadster at auction, one of 53 built. Explore the listing details and history.

A rare 1957 Mercedes-Benz 300Sc “Einspritzmotor” Roadster is currently offered on Bring a Trailer, and bidding has already climbed beyond $200,000 with several days remaining before the auction closes.

This example represents one of the most exclusive post-war Mercedes-Benz models, built in extremely limited numbers. The W188-series 300Sc Roadster stands out even within that range, as production figures list just 53 roadsters produced, making it one of the rarest factory configurations of the model.

Power comes from a 3.0-liter M199 inline-six equipped with Bosch mechanical direct fuel injection, a major technical highlight that defined the 300Sc and earned it the “Einspritzmotor” designation. Factory output for the injected engine was rated at 175 horsepower, an impressive figure for the mid-1950s and a key reason the car remains so historically significant today.

The engine is paired with a four-speed manual transmission, and the listing discussion clarified an important detail: the car uses a floor-mounted shifter, not a column-shift arrangement as originally described.

The roadster was refurbished before being acquired by the selling dealer in 2025. It is finished in Tobacco Brown over a cream leather interior and comes equipped with features including a Becker Mexico radio, wood trim throughout the cabin, and a tan convertible top. The sale also includes fitted luggage, spare parts, literature, and a tool roll.

Adding to the appeal is the car’s ownership history, as it was previously owned by E. Duke Vincent, a former Blue Angels pilot and television producer. While provenance alone rarely defines a car’s value, it often adds an extra layer of interest in the collector market—especially when paired with rarity and period-defining engineering.

With its low production numbers, injection-equipped flagship drivetrain, and high-end craftsmanship, the 300Sc Roadster remains one of the most distinctive Mercedes-Benz offerings of its era. Judging by the current momentum of bidding and strong attention from watchers, the final result may further reinforce the W188’s position in the upper tier of the classic car market.
