This 1978 Eldorado Biarritz not only represents the last of the giant luxury coupes from Cadillac, ut presents as a high-quality survivor that has been expertly maintained from the day it rolled out of the showroom. Big luxury cars are usually treated like something special by their owners, ut this car has received the kind of care usually reserved for cars with an extra zero on their price tag.Cadillac sent the Eldo off in fine fashion in 1978, s in 1979 there would be an all-new smaller personal luxury coupe, nd the Biarritz Classic (AKA "Collector's Edition") was the top-of-the-line. Mediterranean Blue Firemist paint manages to be both flashy and elegant at the same time and seems to emphasize the Eldorado's truly massive proportions. At nearly 20 feet long and 5000 pounds, his was full-sized American luxury on a scale unseen for the past 35 years. Hailing from a warm, ry climate, his car still sports its original paint over laser-straight factory sheetmetal, nd even the plastic fender extensions are in outstanding shape, lthough they've aged a bit and don't quite match the bodywork anymore. The Biarritz was highlighted by custom trim along the beltline and highlighting the dip just behind the doors. A padded opera roof that remains unmarked and supple was another part of the Biarritz package, s are the relatively subtle "Biarritz" badges. The chrome is in excellent condition, s are the lenses, hich have delicate Cadillac emblems etched into their surfacesFull-scale luxury was the order of the day inside, nd with room for six, he big Eldorado is more like a living room on wheels. Pillow-tufted leather seats, ncluding a split bench with power actuators for both driver and passenger, ie it together with the exterior, nd the "Sierra Grain" leather upholstery adds a layer of comfort and luxury that you have to experience to believe. Instruments, auges, nobs, nd handles all leave no question that this is a well-cared-for original car, ith crisp markings on the gauges and beautifully sharp knobs featuring Cadillac wreaths on their faces. Creature comforts abound, rom automatic climate control to power windows and locks to cruise control and an AM/FM stereo radio with factory CB (how cool is that?). And feel free to bring everything you can carry on road trips, ince the trunk is massive and still carries its original spare tire and jack assembly.Amusingly, he 425 cubic inch V8 under the hood is the "smaller" engine used in the first-generation FWD Eldorados, ut its true calling card is effortless torque. With nearly 5000 pounds to move around, t is a silent, bedient servant that starts easily and purrs along with nary a whisper. The engine bay is just about what you'd expect from a car that's always been loved, howing expert maintenance from day one. Cadillac Blue paint is a bright complement to the satin black engine bay, nd all the belts, oses, nd other accessories are just as Cadillac made them in 1978. The transmission is a TH425 3-speed automatic, hich is basically a TH400 sitting next to the engine and connected to the engine by a massive chain and driving a differential set just ahead of the oil pan. Four-wheel discs, quiet single exhaust with catalytic converter, nd shockingly clean floors round out the chassis. Special Eldorado-only 15-inch wheels wear color-matched hubcaps and 235/75/15 whitewall radials.These big cars are gaining popularity, nd if you're looking for an affordable investment-grade Eldo, ick this one up while it's still a bargain.
