Buick Roadmaster Convertible Coupe
Throughout its history, Buick has remained synonymous with prestige, style, advanced engineering and good value. In particular, the Roadmaster topped the Buick model line between 1936 and 1958, representing a clear expression of its owner’s upward mobility.
The popular Roadmaster was completely redesigned in 1954, now sharing the new C-body platform in common with the Super. Updated for 1957 with a new body and a lowered roofline, the Roadmaster was available in sedan, coupe and convertible models, all receiving Buick’s distinctive ventiports, dashing sweepspears and Dagmar bumpers. The “Nailhead” V8 engine was developed into a 364 cubic inch, 300-horsepower powerhouse by 1957 and, when mated to the Dynaflow automatic transmission, allowed for strong acceleration. Contemporary road tests found the Roadmaster capable of accelerating from rest to 60 mph in just over 10 seconds, en route to a top speed of 120 mph.
