Cadillac introduced the 11th and final generation of the Eldorado for the 1986 model year. Compared to the model it replaced the eleventh-generation Eldorado was again downsized, losing about sixteen inches in length and 350 pounds in weight it what was again a badge-engineered variant of the Oldsmobile Toronado, Buick Riviera, and four-door Cadillac Seville. Annual sales of the Cadillac Eldorado plummeted 72% from 1985 to 1986.  Observers noted this Eldorado represented was too small for Cadillac’s traditional customers yet too soft to attract buyers from competitors from BMW and Mercedes-Benz.

Despite its smaller exterior size, the Eldorado’s interior volume remained comparable to the previous generation model and Lincoln’s Mark VII. For the first time, the Eldorado abandoned its “hardtop” heritage and featured framed door glass. News reports later indicated GM had been led by a consultant’s prediction that by 1986 gasoline in the U.S. would be at three dollars per gallon and that smaller luxury cars would be in demand.  In fact, gasoline prices ended up being half that cost at the time.

1991 was the final year for the eleventh generation Eldorado and also the first year for Cadillac’s new 4.9 liter V-8 engine. Featuring port fuel injection, this engine was mated with GM’s 4T60-E electronically controlled four-speed transmission. The Cadillac-exclusive “viscous converter clutch” provided even smoother shifting under hard acceleration. Engine controls were monitored by the GMP4 powertrain control module (PCM), an onboard 64-kilobyte computer. A new exhaust set-up with a wider catalytic converter reduced restriction by 38% from last year, while the 0-60 mph speed went from 9 seconds in 1990 to 8.2 for 1991. Revised engine mounts prevented engine noise and vibration from affecting the cabin, while the new Computer Command Ride (CCR) system, optional on most other Cadillac models, was standard on Eldorado. CCR would automatically adapt the suspension mode with regard to vehicle speed for better handling and ride comfort. A $309 electrically heated windshield was new to the options list this year, as was the available ($480 on base Eldorado, no charge on Biarritz or touring coupe) “security package,” which now included remote keyless entry along with automatic door locks with central unlocking, and the theft-deterrent system. The Bosch II anti-lock braking system, previously a $925 option, was made standard this year, as well as a more powerful 140-amp alternator. A revised windshield washer system rounded out the changes for 1991.

The base price was $31,245, an increase of almost $2,400 up from 1990, but the jump was not nearly as dramatic when considering the new powertrain and sophisticated suspension system, and that anti-lock brakes were now standard equipment, as well as other previously optional items that were now available at no charge. To exhaust parts inventory – and to make the Eldorado appear to be a better value in its last year of current style production, several optional items were available at no charge on the base Eldorado, including a choice of full vinyl roof covering or full-cabriolet (convertible-look) roof (an otherwise $1,095 option), leather upholstery with power passenger recliner, and the Delco-Bose sound system – with choice of CD or cassette. Additionally, both the $2,050 touring coupe and the $3,180 Biarritz package included the Delco-Bose stereo at no additional charge. 1991 was the final year for the Eldorado Biarritz. Production dropped to just 16,212 (including 2,249 touring coupe models), the lowest for any Eldorado model since 1966.

The current caretaker of this 1991 Cadillac Eldorado Biarritz reports he’s owned the car for nearly twenty years and, during his ownership, has kept the car stored indoors when not in use and can provide maintenance records during his ownership.  What impressed us most is how the condition of this car belies the nearly 95K original miles driven. In addition to being highly detailed, this 1991 Cadillac Eldorado Biarritz is a rare “slick top,” i.e. it does not feature a glass moon roof that most of these cars came equipped with.
