What is the Buick Century?

The Century was a Buick model offered in North America in several eras. The fifth and sixth generations were front-wheel-drive cars: the fifth came in coupe, sedan and wagon forms, while the sixth was a four-door sedan. It served as a practical, mid-size choice in Buick’s range.

The fifth-generation Century adopted a more compact front-wheel-drive layout, and the sixth generation continued on the W-body platform with a sedan body. The Century’s North American run ended in 2005, when Buick replaced it with the LaCrosse.

Century generations

The fifth generation ran from 1982 to 1996, followed by the sixth from 1997 to 2005. The fifth-generation range included coupe, sedan and wagon body styles; the sixth was a four-door sedan. The change brought a new platform and a more contemporary shape, while the Century remained a mid-size car.
