Fleetwood Cadillac History 1981

Fleetwood Cadillac Moels & History 1981

Differing mainly in dimensions from DeVille and Fleetwood, carrying the new crosshatch grille, limos could not have the diesel engine option. Both standard and Formal Limousine models included a dual accessory panel so rear passengers could adjust the climate control and power windows. The formal edition held a sliding glass partition, with seating for seven. Standard limos held eight. Interiors came in dark blue Heather cloth, or black in the back. All carried two fold-down auxiliary seats.
