Buick, one of the most important brands in the world and the oldest in the United States, is still active and now produces cars that are completely in tune with the technological innovations and demands of the times. However, without a doubt, it has managed in the past to impress the public with its massive and powerful models. A typical example of this is the hard-to-find 1955 Buick Roadmaster Convertible, which was produced in 4,735 ‘pieces’ and, by the standards of the day, pioneered both design and engineering. A combination of a V8 engine and automatic transmission, an imposing and long body and an open top made it a top choice for the endless American highways.
