The Classic was a single-deck bus developed by General Motors Diesel from its previous-generation New Look design. The "Classic" was nearly identical to the New Look from the belt rail up, but sported a new front which allowed for a wider front door. The design was originally intended solely for the Canadian market as an alternative to the unpopular Rapid Transit Series (RTS) but ultimately the Classic, produced from 1982 to 1997, met with widespread success in both Canada and the United States. It was available primarily as a 40-foot (12.19 m) long, 102-inch (2.59 m) wide coach, although 16 60-foot (18.29 m) long articulated Classics were manufactured. The design was fairly conservative, yet contemporary and less controversial than the RTS.

The GM New Look bus is a municipal transit bus that was introduced in 1959 by the Truck and Coach Division of General Motors to replace the company's previous coach, retroactively known as the GM "old-look" transit bus.
