Cadillac promoted the 1976 Eldorado Convertible as the last convertible it would ever produce, only to renege on that promise a few years later.

The 1976 Cadillac commercial we’re including here is an enjoyable one, in our book anyway, as it features two Cadillac convertibles from the classic era along with the star of the show, the Eldorado Convertible. GM’s luxury division heavily marketed the ’76 Eldo as the last convertible it would ever produce, and therefore a collector’s item—hence the two classic Caddys in the production.

But then a mere eight years later, Cadillac reversed its decision and returned the Eldorado ragtop to the product line for ’84 and ’85. (While the conversions were performed by ASC, these were official factory products.) Some disgruntled Cadillac owners even pursued a class-action lawsuit against General Motors for the renege, but they were unsuccessful. Like all ’76 Eldorados, the convertible is indeed a collector’s item today, but there will always be an asterisk next to the last convertible claim.

Nonetheless, the ’76 Eldorado drop-top was a large, heavy, and impressive machine, a full 224.1 inches long, on a 126.3-inch wheelbase with nearly 5,000 lbs of curb weight. Meanwhile, the bulky exterior sheet metal seems intentionally styled to make it appear even bigger and heavier than that, while the 500 cubic-inch V8 and the $11,000 base price proclaim that this was every inch a Cadillac. The division did stay true to its word in limiting production to 14,000 cars, including a final run of 200 Bicentennial editions in white with red and blue pinstriping. Now let’s check out the Cadillacs.
