Lowered DeVille Convertible 429ci V8 Automatic Air Conditioning

The 1966 Cadillac DeVille convertible is everything that made the era great. Massive proportions. Big-block torque. A ride so smooth it feels like cheating. Cadillac had long since mastered the formula by the mid-sixties, and this generation DeVille delivered style, substance, and road presence in a package that made no effort to be modest. This particular example turns the luxury up even further with a lowered stance, massive wire wheels, and a blue-over-blue color combo that makes it hard to ignore. It's clean. It's tasteful. And it's unmistakably Cadillac.

Wearing a shade of blue consistent with its factory-correct Marlin Blue finish, this DeVille pairs the exterior with a matching blue convertible top and interior. The result is a striking, cohesive presentation that highlights Cadillac's luxury palette for 1966. A lowered suspension sets the stance just right, and 20-inch wire wheels wrapped in Michelin Pilot Sport A/S tires sharpen the look without overwhelming the lines. Brightwork is in excellent shape overall, from the wraparound bumpers to the signature stacked headlights and blade-style vertical taillights. There are no tacked-on badges, stripes, or trim gimmicks here. Just Cadillac's original sheetmetal with the kind of presence that does the talking for you. A matching vinyl top boot covers the convertible top when lowered, keeping the look clean and tidy while showing off the car's long rear deck. Subtle fender skirts accentuate the already stretched proportions.

Pop the hood and you'll find the factory-style 429 cubic-inch V8 paired with a TH400 3-speed automatic transmission. Cadillac rated this motor at 340 horsepower and a whopping 480 lb-ft of torque when new, and it still delivers the kind of torque-rich cruising that defines the breed. The engine bay is tidy and correct, with a single 4-barrel carb, black-finished air cleaner, and factory-style accessories all intact. Power feeds into Cadillac's heavy-duty rear axle with a 2.94 limited-slip differential, and the car rides on coil springs at all four corners. Power drum brakes and power steering keep the driving experience true to Cadillac form, and the single-exit exhaust runs through a factory-style muffler for a smooth, mellow tone. This one was clearly built to drive. The engine runs strong, the transmission shifts as it should, and the car was just professionally detailed and sorted.

Inside, it's all original Cadillac luxury with the right amount of patina. The blue vinyl upholstery remains in great shape, with matching door panels, dash, and carpet throughout. The cabin features power windows, power locks, a working factory AM/FM radio, ice-cold factory A/C, and a power convertible top that operates correctly. Even the original clock is still in place. A pair of removable center consoles with integrated cupholders give it some daily comfort, but the rest of the cabin stays true to Cadillac's 1966 design language. No screens, no gimmicks. Just plush, padded comfort and more room than most new SUVs. The view over the long hood is every bit as majestic as you'd hope.

This DeVille presents as a clean, honest cruiser that's been tastefully modified without losing its identity. The bones are good, the stance is killer, and it's clearly been cared for over the years. Stored indoors in a climate-controlled garage, it's ready to enjoy as-is or use as a platform for something more radical. Either way, it's a guaranteed head-turner with a classic pedigree.
