1931→1933 Mercedes-Benz 370 S

Mercedes-Benz offered the 370 S as a short-wheel-base drivers car that was built alongside the larger 350, 380 and 370K models. It was officially rated at 15/75 HP and was produced shortly after the merger between Mercedes and Benz.

Many of the 370 S chassis received Sport Cabriolet bodywork from Mercedes-Benz that paved the way for even more dramatic cabriolets on the 500 K chassis.

Auction Sales History


1931 Mercedes-Benz 15/75 PS Mannheim 370 S Roadster U 83903 – sold for €552,000

This particular example was first owned by Union Automobil GmbH in Berlin and then by an architect in Stuttgart. Its third owner was a cinema manager and its the fourth a film producer in Bavaria. The current owners discovered the Mannheim in the mid-1960s. They had just finished restoring another 370 S and were told about this car, which was stored in a garage next to a film studio. (The number plates from their first 370 S are currently on this one). After some 13 years of trying they finally managed to buy it in 1978.

A ‘frame off’ restoration was commenced in 1985 in the course of which a new fuel tank was made in stainless steel, the lighting and interior leather restored, and the woodwork and electrics renewed. Otherwise the car remains outstandingly original, its rust-free body having required no welding (see photographic record on file). One particularly noteworthy feature is this car’s shallow windscreen, which is 11cm shorter than those of other cars in this series, and contributes to its sporting appearance. The restoration was finished in 2000, since when the car has been driven only some 300-500 kilometres, remaining on display in the vendors’ garage at other times. Originally black but strikingly refinished in two-tone white/red with red leather interior, ‘83903’ represents a wonderful opportunity to acquire one of these rare Mannheim sports cars.
