Mercedes-Benz Benz 18 PS Doppelphaeton
The 18 hp Benz was the successor to the 16/20 hp Benz "Parsifal" of 1903. The "Parsifal" series was the response from Benz & Cie. to the successful Mercedes automobiles built at Cannstatt and which influenced its new design. The new generation of Benz vehicles took over from the old, taller-limbed models.
