French automaker Bugatti built roughly 800 Type 57s from 1934 to 1940, making the model its most popular. Ironically, one variant — the Type 57 Atlantic Coupe — is among the rarest and most valuable automobiles in the world. Just four were ever constructed, and three are accounted for today, making chassis 57453 a potential “barn find” that Bugatti estimates could be worth as much as $114 million.

Jean Bugatti was the eldest son of company founder Ettore Bugatti, and by the early 1930s was penning most of the company’s body designs. To modernize the boutique automaker, Jean created the Type 57, which would be built in standard and lowered chassis, and would serve as the basis for everything from luxury touring cars to racing cars and show cars, like the stunning 1935 Bugatti Aerolithe concept.
