Regal

The Buick Regal launched in 1973 on the Colonnade A-body and ran into the 21st century. The 1978–1987 G-body Regal is the most collected generation today, particularly the 1982–1987 turbocharged Grand National and GNX cars — the 1987 GNX was the quickest American production car of its year and remains a major collector target.
