The Mercedes-Benz 770, often referred to as the “Großer Mercedes” (Grand Mercedes), represents the pinnacle of pre-war luxury and engineering from Daimler-Benz. Launched in October 1930 at the Paris Motor Show, this prestigious vehicle was designed to meet the most discerning demands of its elite clientele. The heart of the 770 was its powerful eight-cylinder inline engine, a marvel of its time, displacing a substantial 7.7 liters. Customers had the choice between a naturally aspirated version producing 150 horsepower or a supercharged variant delivering either 150 hp or an impressive 200 hp. Interestingly, the allure of forced induction was strong, with only a mere thirteen buyers opting for the non-supercharged engine.
Production of the meticulously crafted 770 was undertaken at the Mercedes-Benz plant in Untertürkheim, Germany. The initial series, designated W07, spanned from 1930 to 1938, with a total of 117 units produced. As the world moved towards war, the W150 variant of the Mercedes 770 continued production into 1943, adding a further 88 vehicles to the exclusive lineage of the Großer Mercedes.

Mercedes-Benz 770 on the Auction Block: A History of Value
The rarity and historical significance of the Mercedes-Benz 770 have made it a sought-after collector’s item, frequently appearing at prestigious auctions worldwide. Its value reflects not only its engineering and luxury but also its place in history.
One notable example is a 1931 Mercedes-Benz 770 Cabriolet D (W 07) with coachwork by Sindelfingen. This particular model, chassis number ‘85205’, was originally delivered to the renowned German actor Erik Charell. Remarkably, only 18 units of the Cabriolet D were ever produced, adding to its exclusivity. This specific car, after passing through various owners and undergoing restorations, sold for an impressive €2,311,500 at a Bonhams auction in 2015. This sale price underscores the desirability and investment potential of these classic Mercedes-Benz vehicles.
Another significant auction offering was a 1943 Mercedes-Benz 770 K W150 Pullman Limousine. This model is even rarer, with only nine Pullman Limousines built, and this example is considered one of only three surviving and operational. Despite its historical importance and impeccable condition, this Pullman Limousine did not sell at a 2010 Gooding & Company Pebble Beach Auction, even with a high estimate of $1,430,000. This instance illustrates that even for vehicles of this caliber, achieving a sale is not always guaranteed, although it does not diminish the inherent value and prestige of the Mercedes-Benz 770.

The Mercedes-Benz 770 “Großer Mercedes” remains an icon of automotive history. Its combination of powerful performance, luxurious appointments, and limited production ensures its place as one of the most desirable and valuable classic cars in the world.
