1968 Pontiac Grand Prix

Redesigned again in 1968 with a peripheral front bumper, pointed nose, split grille, new tail lamps, new interior and instrument panel. The rear side window lost its sharp trailing edge, a Grand Prix signature design. New wheel discs and pencil-thin whitewall tires were also introduced. This would be last year that the Grand Prix would be based on the B-body.
