The Buick Regal is a mid-size car introduced by General Motors for the 1973 model year. North American production ended in 2004 and began again in 2011. For the 2011 model year, Buick re-introduced the Regal to the North American market, positioned as an upscale sport sedan. Production and sales in China have continued since 1999. For certain model years between 1973 and 2004, the Regal shared bodies and powertrains with the similar Buick Century. Buick had been the first GM division to bring a personal luxury car to market with its full-size 1963 Riviera but was otherwise slow to react to the developing lower-priced mid-size personal luxury market, which Pontiac created with the 1969 Grand Prix and Chevrolet with the Monte Carlo the following year, 1970. At the same time Oldsmobile added a formal notchback coupe to its intermediate line, the Cutlass Supreme, in 1970 and that model soon became Olds' best selling intermediate.
