1977 Fleetwood Cadillac history

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.
