In 1985, the last year of production, the X-body Skylark was available only as a four-door sedan in Custom or Limited trim, as the two-door coupe was replaced by Buick's new Somerset Regal coupe, built on GM's new N-body platform, shared with Pontiac's revived Grand Am and the new Oldsmobile Calais. For 1985 the grille was again redesigned, as was the rear. The taillights were wider and the license plate was moved down to the bumper, while a "Buick" plate appeared where the taillights had been.
