The Sixty-Special Fleetwood sedan was, again, distinguished by chevron slashes of bright metal on the sides of the roof "C" pillars. Also seen were full-length bright metal underscores, clean side styling, a rear end quadrant pattern grille and Cadillac crest medallions toward the back of the rear fenders. Standard equipment included all normal 6300 sub-series features, plus power ventipanes.
