The twin posh “Flagships of the Cadillac fleet” carried styling alterations similar to the “lesser” Fleetwoods. New electronic leveling control was standard. Six-way power driver’s seat controls were now in the door armrest. Standard limos sat eight. The seven-passenger Formal Limousine had a standard divided 45/45 front seat with black leather seating, plus a sliding glass partition. Both models had two additional fold-down seats. Florentine velour upholstery was offered in light gray, black, or dark blue. The Automatic Climate Control System could be operated by driver or passengers. A Dual Accessory Control Panel also let passengers operate the power windows — a logical decision, to be sure. A padded Elk Grain vinyl roof was standard. Not quite as many Formal limos were built as the standard variety. Chrome landau bars were available by special order. So were a full landau roof or cabriolet roof, both in padded Elk Grain vinyl. The landau option offered closed-in rear quarters and a smaller back window. as well as opera lamps.
