Cadillac's non-limousine style Fleetwood model carried the Sixty Special designation in script below the Cadillac crest on the sides of the front fenders. A Fleetwood name also appeared on the rear face of the deck lid. Solid chrome exhaust extension trim moldings were seen on the rear fenders.

Side trim on the long-wheelbase Fleetwood models was about the same as 1956, except for the addition of exhaust extension moldings on the rear fender. This trim ran along a tapering conical flare from above the wheel housing to the rear bumper. A Fleetwood script appeared on the deck lid and limousine styling was seen again. Changes in grilles and bumpers conformed to those used with other series. Both models had auxiliary seats and the Imperial sedan again featured a glass driver's partition. Standard equipment on all Cadillacs was comparable to that included the previous year.
