What is a Gran Sport?
A Gran Sport is a name used by Buick to denote sportier models. The name was often abbreviated to GS. The first GS was introduced in the early 1960’s. The name vanished after 1975 only to be reintroduced in the late 1980’s on the front-wheel driven Regal. I’m no fan of front wheel drive these cars have little or no relation to the old GS other than name.
