This 1976 Cadillac Fleetwood Series 75 limousine (chassis 6F33S6Q178796) is a final-year tenth-generation example and an easy contender for largest-ever American production car, measuring in at 252 inches from stem to stern, or nearly two feet longer than the already-massive Sixty Special of the same era. Finished in a suitably conservative shade of Commodore Blue Metallic that’s believed to be the original paint finish, the car looks well preserved throughout, and the ad claims just 29k original miles. Full functionality is also noted, including luxury niceties like multi-zone climate control with A/C and a privacy divider. There’s little word on the car’s past, but its massive 500ci V8 is said to run well–still, don’t expect much more than 9 mpg, even with a light touch on the throttle. Find it here on eBay in Howell, New Jersey with a $16,500 BIN.
Although 1976 was the final year of the tenth-generation Series 75, a number of standard and optional features debuted for the year, along with over a dozen new colors. Commodore Blue Metallic, as seen here, was one of them, replacing the previous, highly similar Monarch Blue. The seller of this limousine describes condition as being quite nice, noting paint that shows well for the most part, but with a few areas of age showing. Whitewall tires are said to have been recently replaced, and all of the windows are listed as operational. Visual changes for 1976 included different corner and taillights, and while cross-spoke wheel covers remained standard, the turbine style set seen here were optional.
Most of the glass looks like factory Soft Ray tinted style, and although it’s common to see these with the optional padded vinyl roof, we think the design cleans up nicely without. Note how the rear doors cut into the roof.
The front portion of the cab, reserved for the chauffeur, shows well with wear that seems commensurate with the low mileage claim. Just about everything in view looks factory as well, including leather upholstery on the bench. The optional Twilight Sentinel might also be present, which was Cadillac’s marketing term for automatic headlights, a feature that initially debuted for the 1960 model year and is not to be confused with the Autronic Eye dimming system later rebranded Guidematic Headlamp Control.
The rear portion of the cabin is spacious, and in a very old fashioned way, trimmed in cloth rather than leather–during the early 20th century, limos and town cars were often open in the front, and thus specified more weather-resistant leather for chauffeurs and wool or similar for passengers. Two different upholstery styles were offered for this model year; Medici crushed velour in black or blue, or light grey Magnan knit as on display here.
The rear bench can accommodate three passengers if necessary, but is intended for two, both of which are treated to their own standard footrests. In addition to the power glass partition, those riding in the rear have controls for the radio, their own climate control and more. Entry illumination was optional, along with automatic door locks that activate when the transmission is shifted into drive. Condition looks good here as well, despite a lighter color. Side windows are powered, but the rear quarter glass is fixed, and in all, there are a total of four ashtrays and four cigarette lighters.
The 500ci V8 is not photographed, but equipment for this period included a Rochester Quadrajet carburetor and emissions-stifled output of 190 hp and 360 lb. ft. of torque, a serious drop from the 400 and 550, respectively, developed by earlier 500s. A 3-speed automatic sends power to a limited-slip rear which was standard for this model year. The seller says this Series 75 limo benefits from recent mechanical attention, and go on to claim no leaks or odd noises, along with great running and driving behavior.
