STORY

The Century nameplate dates to 1936, but it was revived as a mid-size model that ran through several eras, from mid-size Colonnade coupes and sedans in the 1970s to a long-lived front-wheel-drive W-body sedan. The final generation, built from 1997 to 2005, was a value-oriented family sedan powered by the long-running 3.1-liter V6 and aimed at traditional, comfort-first buyers. It was replaced by the LaCrosse when GM consolidated its mid-size Buick offerings.
