The fourth-generation Buick Roadmaster carried the marque's big-car ambitions in a lower, more flowing shape. Its Fastback bodies traded upright formality for a sweeping roofline, without giving up the long-wheelbase comfort buyers expected.
A Buick Roadmaster engine of this era was a large-displacement gasoline unit built for effortless pulling rather than high revs, as the 5.3 MT Fastback shows. The powertrain sends drive rearward through a manual transmission, so rear-wheel-drive traction and unhurried, torque-led progress define how it feels.
