1928 Mercedes-Benz 370 S Mannheim Sport Cabriolet
- Engine
- 3.7L inline six-cylinder, dual carburetors, 75 bhp

The Mercedes-Benz 370 S Mannheim Sport Cabriolet (chassis/engine 87058) is an early example of the first touring model produced by the merged Daimler-Benz concern, bodied in the desirable two-seat Sport Cabriolet configuration. Originally ordered through the Vienna agency for an Austrian aristocrat, it passed through noble European ownership before arriving in the United States in the early 1960s. It became a centrepiece of San Francisco's Mercedes-Benz community under Jules Barsotti, founder of European Motors, winning Best in Class at the 1977 Pebble Beach Concours d'Elegance and appearing in the 1986 Mercedes-Benz Centennial Exhibition at the Natural History Museum of Los Angeles County.
