The GM "Buffalo" bus is a colloquial term referring to several models of intercity motorcoaches built by the GM Truck and Coach Division at Pontiac, Michigan, between 1966 and 1980. "Buffalo" coaches have a stepped roof in front, and the first three rows of seats are at different levels, mounted on stepped floors resembling some types of theater seating.
