1978 Cadillac Eldorado Custom Classic Biarritz

Attention Cadillac collectors!! Here is something that is not only unique, but perfectly preserved and only has delivery miles. This is an all-original 360 mile 1978 Eldorado Custom Classic Biarritz. Thats right, 360 miles!! This is possibly the low miles Eldorado in existence today. For details and information, contact Ken Baker at 561-866-1601.

The Eldorado Custom Classic Biarritz was a one-year only model to commemorate the end of the traditional sized large Eldorado. Only 1499 of these special cars were produced. They were quickly sold out, as it was the last opportunity to buy the Eldorado that was so loved by many.

We have had this model before and they are sold quickly to collectors. This one is the lowest miles one we know of. With the exception of the bumper fillers, this car is 100% original. The bumper fillers have been replaced.

Everything in this car is exactly as it was when it sat on the showroom floor in a Cadillac dealer. It defies its age and it virtually flawless. We have spent hours examining this car and its almost impossible to find a flaw. It has never had any paint, chrome, or leatherwork. Its all-original, unrestored and preserved. This car is perfect for the Cadillac collector, museum, and will qualify for a preservation class at any concours.

About this Eldorado Custom Classic Biarritz; from Automotive Milestones:

1978 would be the final year for the full-sized Cadillac Eldorado. Demand for more fuel efficient vehicles led General Motors to down size most of its line for 1977, and that left just two of its personal luxury modelsthe Oldsmobile Toronado and the Cadillac Eldoradoto be down sized. (Buick's Riviera was restyled in 1977 and became a mid-sized car.) New smaller versions of the Toronado and Eldorado would happen for the 1979 model year, which meant 1978 would be the final opportunity to buy a new full-sized car from GM.

For the 1978 model year, Cadillac initially offered three Eldorado models: the Coupe, the Cabriolet, and the Custom Biarritz. To commemorate the final full-size Eldorado, Cadillac Division introduced the Custom Biarritz Classic very late in the model year. The Custom Biarritz Classic was identical to the Custom Biarritz, with the exception of duo-tone pillowed leather interior in Light Beige and Dark Saddle, Dark Beige Leather steering wheel jacket, duo-tone exterior finish in Arizona Beige with Demitasse Brown Metallic accent on hood, doors, and roof, Dark Brown accent striping, and gold-plated "Biarritz" script on the sail panel and deck lid.

The 1978 Eldorado in base trim had a wheelbase of 126.3 inches, weighed 4,906 pounds, and had an overall width of 224.1 inches. Truly, a significant automobile. Power was provided by a 425 cubic inch V-8 engine with a compression ratio of 8.2:1 and a horsepower rating of 180 at 4,000 rpm. Driven carefully, this car can get double digit fuel mileage in town, and in the mid-teens on the highway.

There were other reasons for the Custom Biarritz Classic besides Cadillac's desire to bid farewell to the final full-sized cars with a special edition model. Lincoln was celebrating Ford Motor Company's 75th Anniversary in 1978 with the Continental Mark V Diamond Jubilee Edition, which had been available since the 1978 model introduction, and was selling briskly. Also, Cadillac knew that the final full-sized Continental Mark V would be built in 1979, and a special Collector's Series model based on the Diamond Jubilee Edition was planned for that model's final voyage. This meant if Cadillac were going to provide a proper send off to the Eldorado, they'd have to come up with something quickly. It hardly seemed appropriate to allow the last full-sized Eldor...
