In 1957 the legendary Gullwing was succeeded by the roadster version of the 300 SL. The open sports car – long wished-for mainly by the American clientele – came with regular doors, made possible by a revised space frame with lower frame side members. The newly fitted single-joint swing axle made the high-performance sports car easy to handle even for less experienced drivers.
