Overall Rating
Buick Roadmaster:
The Buick Roadmaster is an automobile built by Buick in three distinct periods: 1936 through 1942; 1946 through 1958; and 1991 through 1996. Roadmasters produced between 1936 and 1958 were built on Buick's longest non-limousine wheelbase and shared their basic structure with the entry-level Cadillac Series 65, the upscale Buick Limited, and, after 1940, the Oldsmobile 98. Between 1946 and 1957, the Roadmaster served as Buick's flagship.
After being resurrected in 1991, the Roadmaster became the marque's largest vehicle, measuring 10 in longer with a 5 in greater wheelbase than the C-body Buick Park Avenue. This generation was the first in Roadmaster history to be built on the General Motors B-body platform rather than the C-body, which up to 1984 had been reserved for GM's largest and most opulent models that were not Cadillacs....(Read more on Wikipedia)
