The 1990 model year Buick Century was the last to receive a major change to the interior. It received a new bumper, bigger radiator grille, and different headlamps. The door panels were restyled as well, and new window switches were installed in the correct locations. Unlike the previous Century, which used a single switch mounted flush with the door panel, the new Buick incorporated a separate window switch for each passenger. The Buick Century also gained standard console shifters in 1992 and 1993.
