Cadillac Service Repair Manuals

About 2,000 limos, offered in standard or Formal form, found buyers each year. Both had the same new crosshatch grille as Fleetwood Brougham, along with new simulated woodgrain interior, a lower profile, and revised two-spoke steering wheel. Fleetwood remained the only American-built chassis for use in "professional" cars used by funeral directors and for ambulances. The basic limo seated eight; the Formal edition, seven. Both were powered by the 425 cu. in. (7.0-liter) V-8, which had to haul over 4,800 pounds of car around. Standard interior was dark blue Dante cloth, but slate gray and black were available. Front compartment of the Formal limo was black, with black leather in seating areas, separated from the passenger compartment by a sliding glass partition. Interiors were also offered in slate gray and black. All limos included two fold-down auxiliary seats. There was a dual accessory control panel for climate control and windows, along with new optional rear seat controls for the radio. An optional 8-track tape player put controls in the back.
