1932 Mercedes-Benz 370 S Mannheim Sport Cabriolet

84919roadGermany
Engine
3.7L inline-six (replacement unit of correct type)

The Mercedes-Benz 370 S Mannheim Sport Cabriolet (chassis 84919) is one of only 195 examples built during the model's brief two-year production run from 1931 to 1933. Dispatched from Weimar to Erfurt by rail in June 1932, it passed through several German owners before being stored on blocks through and after the Second World War. A dealer-led restoration in the 1950s preceded a more thorough recommissioning after 2004 that returned the car to its original 1932 delivery specification. A 2014 Mercedes-Benz Classic Centre expertise confirmed that the chassis, gearbox, and bodywork are all original.

Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections.
