The Buick Regal is an upscale mid-sized automobile that was first introduced by Buick for the 1973 model year. The model was originally positioned as a personal luxury car, and typically offered in both coupe and sedan forms until 1997, when the Regal became sedan-only due to the decline of the personal luxury coupe market.
