Start with what the Mercedes-Benz 770 is: a 4-door, 6-seat Pullman (limousine) / Touring car (6 seats) / Cabriolet with 7,665 , built from 1930 to 1944, when streamlining and independent suspension were arriving together. What it meant takes a little longer.
The story
The Mercedes-Benz 770, also known as the Großer Mercedes (German for "Large Mercedes"), was an ultra luxury car built by Mercedes-Benz from 1930 until 1944. The second model (W150) is best known from its use by high-ranking officials of Nazi Germany and their allies before and during World War II, including Adolf Hitler, Hermann Göring, Heinrich Himmler, Reinhard Heydrich, Ion Antonescu, Gustaf Mannerheim, and Benito Mussolini, many of which were captured in archival footage.
What is underneath
The engine is 7,665 other versions carried different engines, listed in the specification table below. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. The wheelbase is W07 (1930–1938): 3750 mm / W150 (1938–1944): 3880 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Its place in the line
In the Mercedes-Benz line-up the Mercedes-Benz 770 has a clear place: it replaced the Mercedes-Benz 630; it handed the line to the Mercedes-Benz 600; the factory was Untertürkheim, Germany. The cars a buyer would have weighed it against include the Chrysler LeBaron, the Bentley 8 Litre, the Vauxhall Cadet. Nearby in the Mercedes-Benz catalogue sit the Mercedes-Benz 300 SL and the Mercedes-Benz C124.
Owning one today
MotorJury scores cars on the United States complaint and recall record, and the Mercedes-Benz 770 has none: too old, too rare, or never sold there. Its value today is a collector's question, decided by provenance and condition rather than by a class average.
