Background
The Buick Regal is a line of mid-size cars marketed by Buick since 1973. Serving as the premium mid-size/intermediate car of the Buick product range for nearly its entire production, the Regal initially served as the divisional counterpart of the Pontiac Grand Prix and Oldsmobile Cutlass Supreme; since the late 2000s, the model line has been derived from the European Opel Insignia. The Regal also serves as the basis of the high-performance Grand National, Gran Sport (GS), and Buick GNX coupes.
