The Buick Roadmaster was built from 1936 to 1958, and again from 1991 to 1996. Roadmasters produced between 1936 and 1958 were built on Buick’s longest non-limousine wheelbase and shared their basic structure with entry-level Cadillac and, after 1940, senior Oldsmobiles. Between 1946 and 1957 the Roadmaster served as Buick’s flagship.
The origins of the Roadmaster name date to 1936 when Buick added names to its entire model lineup to celebrate the engineering improvements and design advancements over their 1935 models.
