1976 was the end of an era for General Motors as the following year all divisions' full-size cars were due for downsizing the following year. For 1977, the cars became shorter, smaller and lighter. The engines, too, became smaller, with Cadillacs biggest becoming a 425 cubic-inch unit, down from 500 in 1976. 1976 was also the last year (for many years to come) that GM would market a convertible; Cadillac observed the event by selling 200 identical commemorative Eldorado soft-tops.
After a 39 year streak, 1976 was the final time the Sixty Special name would grace a Cadillac.
The DeVille was three inches longer than the Calais model. The Sixty Special Brougham rode on a 133-inch wheelbase and standard equipment included a signal-seeking radio with power antenna, automatic level control, six-way power seat, power windows and door locks and carpeted footrests. All full-size Cadillacs had limited slip differential, automatic climate control, power steering and brakes, Soft Ray tinted glass, and Turbo Hydr-Matic transmission.
This Cadillac Fleetwood Sixty Special Brougham was purchased by the current owner from the Drumheller, Alberta Cadillac dealer on January 17, 1976. It has 49,350 miles, is painted in silver paint, and highlighted by the Brougham appearance package, which dispensed with 'opera windows' in the sail panel in favor of a more traditional look. It has the original 8-track player, a 500 cubic-inch overhead valve V-8, and three-speed Turbo 400 Hydra-Matic transmission.
In 2011, this vehicle was offered for sale at the St John's Auction presented by RM Auctions. It was estimated to sell for $8,000 - $12,000 and offered without reserve. As bidding came to a close, the car had been sold for the sum of $8,800, including buyer's premium.
