What kind of car is the Buick Roadmaster?

The Roadmaster was a large Buick passenger car, offered in its final generation as a sedan and an Estate station wagon. The wagon brought together a roomy cabin and the carrying space of a traditional American estate car.

The name returned to Buick’s range with the third generation, which used GM’s B-body platform. The Estate wagon appeared before the sedan.
