It was time for another facelift this year and, really, a very minor one. New up front was a bi-angular grille that formed a V-shape along both its vertical and horizontal planes. The main horizontal grille bar was now carried around the body sides. Outer grille extension panels again housed the parking and cornering lamps. It was the 17th running season for Cadillac tailfins, with a new, fine-blade design carrying this tradition on. Performance improvements, including a larger V-8, were the dominant changes for the model run. Equipment features replicated those of 1963 for the most part. Introduced as an industry first was Comfort Control, a completely automatic heating and air-conditioning system controlled by a dial thermostat on the instrument panel.
