Other than a slightly revamped grille and rear bumper, 1964 Sixty Special saw few exterior changes. The Cadillac wreath and crest ornament was moved to take the place of the C-pillar mounted louvers. The Sixty Special (and companion Eldorado convertible) featured almost no side trim, except for a wide rocker-sill molding which ran from the rear-edge of the front fender wheel well to the rear of the car. Engine displacement was enlarged to , and the venerable Hydra-Matic transmission, first introduced in the 1940 model year, was replaced with the new Turbo-Hydromatic automatic transmission. The cost was back up to the 1962 price of $6,366, and sales were up to 14,500 units.
