Cadillac's longest, heaviest, richest and highest priced models were, again, more conventionally engineered than the other lines. For example, the new perimeter frame was not in use and neither was the improved automatic transmission. In addition, automatic level control was not featured. Even the annual styling facelift did not affect these traditional-bound luxury cars. They came with all power controls found in Eldorados and added courtesy and map lights to the standard equipment list. Sales of commercial chassis earned an increase of thirty units, while limousine deliveries tapered slightly downward and the popularity of the nine-passenger sedan saw a considerable decline.
