This 1957 Mercedes-Benz 300SL Roadster (chassis 7500469) is one of 1,858 examples produced from 1957-1963.
Finished in silver over black leather, the car is equipped with a black soft top and retains its original drivetrain, including the fuel-injected 3.0L inline-six, four-speed manual gearbox, and differential.
The 3.0-liter M198 straight-six produced 240 horsepower when new and features Bosch mechanical fuel injection, a first for a road car when it debuted.
The iron block is leaned over at an angle of 50° and equipped with dry-sump lubrication.
A mechanical rebuild was carried out from 2017 to 2019 and included blueprinting the block.
A new crankshaft and pistons were installed, along with new rod, main cap, and head bolts.
The timing gear and water pump were renewed, and the two oil pumps were rebuilt in Germany.
The assembled engine was then statically and dynamically balanced.
The four-speed manual gearbox and differential were rebuilt as well.
The W198 was Mercedes’ last body-on-frame design, and chassis 7500469 retains its original body (7500392).
The odometer was zeroed out during the service, as true mileage was already unknown.
