Hoffman's dealers made requests through him, both for existing models and new types they thought their customers would purchase in the booming post-war American market. The most famous result of Hoffman's suggestions is the Mercedes-Benz 300SL "gullwing". More than 80% of the 300SL's total production of approximately 1400 units were sold in the US, making it the first Mercedes-Benz widely successful outside its home market and thoroughly validating Hoffman's seat-of-the-pants prediction. Its success is credited with changing the company's image in America from a manufacturer of solid but staid luxury automobiles to one capable of rendering high-performance sports cars. From 1950 until 1953, Hoffmann was the importer and distributor for Volkswagen for the eastern United States. He was also the importer and sole distributor for BMW from the mid-sixties until selling his business to BMW of North America in 1975. Alfa Romeo was also imported to the United States by Max Hoffman starting from the mid-1950s. The Giulietta Spider was born by request of Max Hoffman. In 1961 Alfa Romeo started importing cars to the United States. The Porsche 356 1955 "Speedster" was the result of a Hoffman suggestion that a less expensive, racier version of the standard 356 would sell well in America. With its low, raked windshield—which easily could be removed for weekend racing, bucket seats, and a minimal, folding top, it was an instant hit. Some of the dealers, such as Lake Underwood and his team's machine engineer, Dick DeBiasse, were especially influential on Hoffman.

In 1982 Marion O. Hoffman established the non-profit Maximilian E. and Marion O. Hoffman Foundation Inc. in West Hartford, Connecticut, in memory of her husband.
