1959 DeSoto Adventurer I Convertible (facelift 1959) Dimensions, Size & Specs

The 1959 DeSoto Adventurer I Convertible has a ground clearance (ride height) of 142 mm (about 5.6 inches). While the exact overall height isn't specified, cars of this era typically had a height around 1,400-1,500 mm (~55-59 inches). The relatively low ride height contributes to improved stability and a sleek, elongated appearance. However, the 142 mm clearance means owners should be cautious on uneven surfaces to avoid undercarriage scraping. The combination of ride height and classic wide-body design ensured that the Adventurer had a commanding road presence, blending performance with elegance.

The curb weight of the 1959 DeSoto Adventurer I Convertible stands at approximately 2000 kg (about 4409 lbs). This hefty weight is typical for full-size luxury convertibles of the late 1950s, which favored solid construction and substantial materials. The weight influences the car's driving dynamics, providing a smooth and stable ride at highway speeds but requiring a powerful engine to deliver adequate acceleration. Consequently, the Adventurer's robust curb weight contributes to its feeling of durability and luxury but demands a capable drivetrain to maintain spirited performance.

A standard single-car garage typically measures around 2.7 meters (9 feet) in width and about 5.5 to 6 meters (18 to 20 feet) in length. The 1959 DeSoto Adventurer I Convertible's length of 5616 mm (5.616 meters or approximately 18.4 feet) and width of 1999 mm (1.999 meters or roughly 6.56 feet) make it a tight fit lengthwise in many single garages but generally inside the typical width limits. Parking this vehicle in a standard garage will require careful maneuvering, especially considering additional room needed for door opening and clearance. Owners with larger or double garages would find accommodating it easier.

The 1959 Adventurer I Convertible was a facelifted iteration of the earlier DeSoto Adventurer introduced in 1958. Dimensionally, the 1959 model maintained the large size characteristic of the preceding generation, with the substantial length of 5616 mm (221.1 inches) and width of 1999 mm (78.7 inches) essentially consistent. This continuity preserved the spaciousness and grand presence of the model. Improvements were mainly stylistic and mechanical rather than size alterations, reflecting DeSoto's focus on luxury and aesthetics rather than downsizing in this period.

Compared to contemporaries such as the 1959 Cadillac Eldorado and the Chrysler 300E convertible, the DeSoto Adventurer I Convertible measured competitively in length and width. Its length of 5616 mm (about 18.4 feet) and width of 1999 mm (6.56 feet) placed it firmly among the largest and widest convertibles, providing ample interior space and imposing road presence. Generally, these models were comparable in size, but the DeSoto was distinguished by subtle styling cues and its balance between luxury and sporting character. Smaller convertibles from other brands offered more agility but less presence.

While exact interior dimensions aren't detailed, the 1959 DeSoto Adventurer I Convertible's large exterior dimensions translate into a spacious cabin. The broad width of 1999 mm (78.7 inches) allowed for comfortably wide front and rear seats, typical of late 1950s full-size American convertibles. The design prioritized passenger comfort with ample legroom, headroom, and shoulder space, enhanced by the open-air nature of the convertible roof. This made it a popular choice for cruising in style with multiple passengers without compromising comfort.

While this FAQ focuses mainly on size, it is notable that the 1959 DeSoto Adventurer I Convertible was equipped with powerful V8 engines typical of the era, often around 345 cubic inches (approximately 5.7 liters), delivering strong horsepower to propel the large frame efficiently. The performance was respectable for a luxury convertible of its weight class (2000 kg / 4409 lbs), combining smooth acceleration with comfortable cruising capability. This solid powertrain supported the vehicle’s sizeable curb weight and ensured driving satisfaction on highways and city streets.

The 1959 DeSoto Adventurer I Convertible has a ground clearance of 142 mm (5.6 inches), which is relatively low, aiding aerodynamic stability and a low center of gravity. This low clearance helps improve handling by reducing body roll during turns but requires careful driving over uneven terrain or speed bumps to avoid underbody damage. The ground clearance complements the vehicle's large curb weight and wide stance, delivering a stable yet comfortable ride, well suited for paved roads typical in urban and suburban settings during the period.

Yes, the 1959 DeSoto Adventurer I Convertible is considered a prized collectible car among classic car enthusiasts due to its limited production run from 1958 to 1959, distinctive styling, and representation of late-1950s American automotive luxury and craftsmanship. Its rarity and stylish design, combined with a robust V8 engine and full-size convertible appeal, make it an attractive restoration project or museum-quality showpiece. However, finding one in good condition can be challenging, and maintaining its vintage mechanical components requires dedication, but collectors prize its cultural and historical significance.
