This 1978 example is finished in elegant Arizona Beige with contrasting brown accents sweeping from the hood across the roofline\u2014an unmistakable and sophisticated presentation. The partial color-coordinated Landau roof, C-pillar opera lamps, chrome brightwork, and factory Astroroof glass sunroof complete the signature Biarritz look.<\/p>\n<p>Inside, the cabin is upholstered in rich two-tone Antique Light Beige and Dark Saddle Sierra Grain leather, featuring power-adjustable Dual Comfort front seats and a matching rear bench. Faux wood trim accents the dash and door panels, while luxury conveniences include automatic climate control, cruise control, power windows and locks, a rear window defroster, power trunk release, and an AM\/FM stereo. A CB radio handset mounted below the dash adds a nostalgic period touch. The horizontal 85-mph speedometer frames an odometer reading just 16,000 miles.<\/p>\n<p>Under the hood rests Cadillac\u2019s 7.0-liter (425ci) V8, factory rated at 180 horsepower and 320 lb-ft of torque, paired with the smooth-shifting Turbo Hydra-Matic three-speed automatic transmission driving the front wheels. The ride is classic Cadillac\u2014gliding and composed\u2014thanks to torsion bar front suspension, a coil-sprung solid rear axle, Electronic Level Control, and power steering. Stopping power is provided by four-wheel disc brakes.<\/p>\n<p>Recent service in 2023 included replacement of the thermostat, radiator cap, alternator, battery, windshield washer reservoir, passenger-side exhaust manifold, front shocks, heater core, heater control valve, and air-conditioning components. The transmission was serviced with fresh fluid and a filter in August 2023. The car rides on 15-inch steel wheels with body-color covers wrapped in American Classic whitewall tires, perfectly complementing its period-correct appearance.<\/p>\n<p>This Eldorado Biarritz captures the essence of Cadillac\u2019s golden era\u2014refined, commanding, and unmistakably luxurious. Whether displayed at a show or enjoyed on a relaxed weekend cruise, it delivers the presence and comfort that defined American motoring in the late 1970s.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>1978 CADILLAC ELDORADO BIARRITZ \u2013 7.0L V8 | 16K Miles HIGHLIGHTS \u2022 7.0-Liter (425ci) V8 \u2013 4-Barrel Carburetor \u2022 Turbo Hydra-Matic 3-Speed Automatic Transmission \u2022 Arizona Beige (62) with Brown Accents \u2022 Two-Tone Antique Light Beige &amp; Dark Saddle Sierra Grain Leather \u2022 Power-Operated Astroroof Glass Sunroof \u2022 Partial Body-Color Landau Roof with Opera Lamps [&hellip;]<\/p>\n","protected":false},"author":15796,"featured_media":1972657,"comment_status":"open","ping_status":"closed","template":"","meta":{"content-type":""},"product_cat":[18],"product_tag":[797,157,54],"class_list":["post-1972656","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-auctions","product_tag-cadillac","product_tag-eldorado","product_tag-classic-car-auctions"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 -
