The Mercedes-Benz 770, often referred to as the ‘Großer Mercedes’ or ‘Grand Mercedes’, was unveiled in October 1930 at the Paris Motor Show, immediately setting a new benchmark for luxury and performance. Designed to satisfy the most discerning clientele, this magnificent vehicle was powered by a substantial 7.7-liter inline-eight engine, offered in both naturally aspirated (150 hp) and supercharged (200 hp) versions. Interestingly, only a mere thirteen buyers opted for the non-supercharged variant, highlighting the demand for ultimate power and prestige in this era of automotive excellence.
Production of the initial 770 series, known under the chassis code W07, took place at the Mercedes-Benz plant in Untertürkheim from 1930 to 1938. During this period, a limited run of just 117 cars were meticulously hand-assembled, emphasizing the exclusivity and bespoke nature of the model. The subsequent W150 generation, launched in 1938 and continuing until 1943, added a further 88 units to the total production, navigating through the challenging wartime environment while maintaining the model’s iconic status.

The Allure of Auction History: 1931 Mercedes-Benz 770 at Auction
The enduring appeal of the 1931 Mercedes-Benz 770 Grosser is further cemented by its performance in the classic car auction market. One notable example, a 1931 Mercedes-Benz 770 Cabriolet D (W 07) with coachwork by Sindelfingen, chassis number ‘85205’, was sold by Bonhams in 2015 for an impressive €2,311,500. Originally delivered to the renowned German actor Erik Charell, this Cabriolet D was one of only 18 ever produced, adding to its rarity and desirability. Its journey through notable collections, including the Blackhawk Collection, and meticulous restorations have ensured its pristine condition and continued prominence at prestigious concours events.
In contrast, a 1943 Mercedes-Benz 770 K W150 Pullman Limousine, a historically significant model with only three known examples remaining, did not meet its reserve at a 2010 Gooding & Company auction, despite a high bid of $1,430,000. This particular Pullman Limousine, noted for its political connections and status as the last of its kind built, highlights the complex factors influencing the collector car market, where provenance and historical context can play as crucial a role as rarity and condition.
The Mercedes-Benz 770 Grosser from the 1930s remains an automotive icon, representing the pinnacle of pre-war luxury, engineering innovation, and enduring historical significance. Its limited production numbers, powerful engine, and association with significant historical figures ensure its place as a highly sought-after classic for discerning collectors worldwide.
