Model overview

Model description

By 1955, the car line had proven itself and was allotted a special 270 horsepower engine, higher than the 250 offered in other Cadillacs that year. The 1955 Cadillac line may have resembled the 1953 and 1954 cars, but the Eldorado specifically gained longer, taller tailfins not shared with any other Cadillac that year. Sales increased to 3,950, and the price increased slightly to $6,286. 1956 cars included a new Eldorado Seville two-door hardtop coupe, which nearly outsold the convertible two-to-one. Once again, a special 305 horsepower was fitted to the Eldorados, whereas other Cadillacs had to make do with 285 hp. 1957 cars were entirely redesigned with a lower stance. Once again, the Eldorado possessed 325 hp vs. 300 hp for other Caddies. But the big Eldorado news for 1957 was the addition of a fabulously expensive four-door hardtop hand-built variant that cost an eye-watering $13,074. The price tag on the Eldorado Biarritz convertible was just $7,286. A two-door hardtop was also available. Exactly 400 four-door cars were built, and they featured rear-hinged rear doors and Cadillac’s first use of quad headlamps, a stainless steel roof and standard, but problematic, air suspension. It was also the first use of “memory” power seats. There were only minor changes for 1958, although 305 of the top-of-the-line Pininfarina-bodied four-door Eldorado Brougham were built and sold, again starting at $13,074. The Eldorado Seville two-door hardtop and Eldorado Biarritz two-door convertible each sold for $7,500. All cars but the Eldorado Biarritz featured the new front styling with quad headlamps that was unveiled a year earlier.

Many factors can increase a car's value including excellent condition, exceptional originality, a recent restoration, low mileage, unique provenance, desirable options, popular or unique color choices, and excellent maintenance records. Upgrades and modifications that enhance performance or aesthetics can also add value.

Factors that can decrease a car's value include unusually high mileage, poor maintenance history, visible wear and tear, accidents or damage, title issues, and gaps in ownership history. Additionally, less popular color choices and extensive modifications that don't appeal to a broad audience can reduce value.

Mileage plays a significant role in a classic car’s value. Lower mileage usually increases value because it indicates a higher degree of originality, is rarer, and suggests less wear and tear. However, cars with exceptionally low mileage may also have maintenance needs due to lack of use. Whether someone should pay more for a vehicle with lower miles will depend on how they plan on using it, and the vehicle's specific condition.

The value of modified cars differs widely based on the type and quality of modifications. While some modifications can significantly increase value, especially performance enhancements and high-quality custom work, others may not add much or could even detract from the car’s value if they appeal to only a limited audience.
