Exterior and Interior
The exterior of this 1978 Cadillac Eldorado Biarritz is finished in Colonial Yellow and showcases the dramatic proportions and formal styling that defined Cadillac’s flagship personal luxury coupe. The Biarritz trim adds unique exterior details including the padded Landau roof treatment, Biarritz badging, and upscale brightwork, complemented by factory wire wheel covers for a classic Cadillac appearance. The long hood, low roofline, and wide stance create the commanding presence expected from a late-1970s Eldorado. The interior of this 1978 Cadillac Eldorado Biarritz is appointed in Yellow leather and reflects Cadillac’s focus on comfort and luxury. The cabin features plush seating, woodgrain accents, power accessories, automatic climate control, and a driver-focused dashboard layout. A particularly notable feature is the factory Cadillac telephone system, an exclusive period luxury option that highlights the vehicle’s executive character. Additional convenience features include power seats, power windows, and a tilt and telescopic steering wheel.
Engine
Powering this 1978 Cadillac Eldorado Biarritz is a 425ci naturally aspirated V8 engine equipped with electronic fuel injection, delivering the smooth and effortless performance expected from Cadillac’s flagship coupe. Power is sent to the front wheels through a 3-speed automatic transmission, providing relaxed cruising capability and refined operation. Combining front-wheel-drive engineering with Cadillac’s traditional V8 power delivery, the Eldorado Biarritz represents a unique chapter in American luxury automobile history.
The 1984 Cadillac Eldorado Biarritz Convertible is pure old-school American luxury: long, low, formal, and unapologetically extravagant. Showing approximately 66,668 miles, this example is finished in blue over a white leather interior with blue piping and wears a matching white convertible soft top. The Biarritz trim gives the Eldorado an even more upscale presence, while its wire wheel covers, tufted seating, woodgrain trim, and comfort-heavy specification make it feel every bit like the flagship personal luxury cruiser Cadillac intended. It is the kind of car built less around lap times and more around making every drive feel like an occasion.
This 1976 Cadillac Eldorado Convertible is a full-size American luxury cruiser from the final model year of the traditional Eldorado convertible. Finished in White over a White leather interior with red accents and a matching White convertible soft top, it combines unmistakable 1970s Cadillac presence with a 500ci V8, front-wheel drive, and a long list of comfort features. Showing approximately 94,630 miles, this Eldorado also offers automatic climate control, cruise control, power-adjustable seating, power windows, power locks, and the period styling details that made Cadillac convertibles of this era such distinctive road cars.
The 1967 Cadillac Eldorado Coupe represents a landmark chapter in Cadillac history as the brand’s first front-wheel-drive Eldorado generation, combining advanced engineering with the unmistakable presence of a full-size American luxury coupe. Powered by Cadillac’s massive 472ci V8 and finished with elegant proportions, this Eldorado has been customized with a range of upgrades while maintaining its classic character. Finished in White with a White/Brown interior, this example shows approximately 92,444 miles and features a custom paint job, reupholstered interior, aftermarket air ride suspension, upgraded air conditioning system, and refreshed mechanical components reported by the current owner.
This 2019 Cadillac CT6-V represents one of Cadillac’s most ambitious modern performance sedans, pairing flagship-level luxury with the hand-built Blackwing V8 and a chassis developed specifically for serious performance. Finished in Manhattan Noir Metallic over a Dark Auburn leather interior with Jet Black accents, this example combines understated executive styling with V-Series hardware including Magnetic Ride Control, active rear steering, Brembo brakes, an active-valve exhaust system, and extra-capacity cooling. The Rear Seat Package and Driver Assist Package add another layer of comfort and technology, while features such as the Bose Panaray 34-speaker sound system, UltraView power sunroof, head-up display, and 12-inch reconfigurable gauge cluster reinforce its flagship character. Showing approximately 5,060 miles, this CT6-V stands out as a remarkably low-mileage example of Cadillac’s short-lived Blackwing-powered super sedan.
This 1986 Cadillac Fleetwood Brougham delivers the full-size luxury presence that defines Cadillac’s traditional rear-wheel-drive sedan formula. Finished in Cotillion White with a White padded vinyl roof over a Dark Claret Heather Cloth interior, it presents a distinctly formal appearance inside and out. Its equipment includes 15-inch steel wheels with wire-spoke wheel covers, chrome bumpers and bodyside moldings, cornering lamps, power windows and locks, automatic climate control, woodgrain interior trim, an illuminated entry system, and a Sony XR-2300 AM/FM cassette stereo. Showing approximately 92,289 miles, this Fleetwood Brougham combines traditional Cadillac styling with a 5.0-liter V8 and a comfortable, luxury-oriented cabin.
The 2005 Cadillac XLR was Cadillac’s answer to the luxury roadster market of the early 2000s, blending dramatic styling, V8 power, and a distinctly upscale approach to open-top motoring. Showing just 37,731 miles, this example is finished in Crimson Pearl over a Shale interior, a color combination that gives the car a rich, period-correct presence. Under the hood sits a 4.6L naturally aspirated Northstar V8 paired with a 5-speed automatic transmission and rear-wheel drive, while the cabin adds its own sense of occasion through Light Eucalyptus wood accents and XM Satellite Radio. With its low mileage, retractable-hardtop grand touring character, and unmistakably Cadillac presentation, this XLR offers a distinctive alternative to the more common European luxury convertibles of its era.
This 1956 Chevrolet 150 Restomod is a clean Tri-Five build with the kind of mechanical and cosmetic upgrades that make these cars genuinely fun to drive. Showing approximately 3,050 miles, it features a custom Green and White paint job over a reupholstered Brown leather interior and is powered by a 383ci Summit Racing crate V8 paired with a 5-speed manual transmission. The engine has been positioned 1.5 inches forward, while Sanderson headers, a 3.90 Posi-Traction rear end, power-assisted disc brakes, electric cooling, and an aluminum radiator give the car a far more capable setup than a stock 150. Add Dakota Digital gauges, air conditioning, a trunk-mounted battery, 17-inch mag wheels, and an upgraded sound system, and this is a well-rounded restomod that blends classic Tri-Five style with much more modern road manners.
This 1957 Buick Roadmaster Riviera 2-Door Hardtop is pure late-1950s American excess in the best possible way, combining dramatic Harley Earl-era styling with the torque-rich character of Buick’s Nailhead V8. Showing approximately 14,574 miles, this example was refurbished in the late 2000s and is finished in Dover White and Bittersweet Red over a Rust and Ivory interior. Its 364ci Nailhead V8 was overhauled, the Dynaflow automatic was rebuilt, and the car was later upgraded with an Air Lift Performance air suspension system. Add in power steering, power brakes, power windows, a power front bench seat, Hot Rod Air climate control, and wide whitewalls, and this Roadmaster delivers the extravagant look of a flagship ’50s Buick with a few thoughtful upgrades that make it even more enjoyable today.
This 1971 Dodge Charger Restomod Super Bee Tribute brings together the aggressive third-generation Charger shape, period-inspired Super Bee styling, and a thoroughly updated big-block drivetrain.

The centerpiece is a 440ci V8 fitted with FiTech electronic fuel injection and a Mancini Racing Six Pack intake, backed by a TorqueFlite 3-speed automatic and an 8¾-inch Sure Grip rear end with 3.55 gears. Add in the N96 Air Grabber system, AMD bulge hood, Rallye instrumentation, Slap Stik shifter, and Super Bee graphics, and this tribute captures the visual attitude of Mopar’s muscle-car era with a more usable modernized fuel system.
