Fleetwood Cadillac History 1977

Fleetwood Cadillac Models & History 1977

Newly designed Fleetwood and Fleetwood Formal Limousines continued to serve as the “flagships of the Cadillac fleet,” but in sharply shrunken form. The contemporary edition was over a foot shorter and 900 pounds lighter. Large door openings allowed easy entry/exit. Automatic Climate Control could be operated from front or rear. A Dual Accessory Panel let passengers operate power windows and radio, or set temperature. Wheel covers could match any color. Both outside mirrors were remote-controlled. Upholstery choices included ark blue Florentine velour; light gray or black Dover cloth. Formal Limousines had black leather up front, plus a glass partition. Opera lamps were standard. Only 1,299 commercial chassis were turned out this year.
