The 1958 Chevrolet Impala Convertible stands as the definitive launch of a nameplate that would dominate the American automotive landscape for decades. As the top-of-the-line Bel Air sub-series for its debut year, the 1958 model featured a one-year-only body style that was longer, lower, and wider than its predecessors. This particular example is a highly finished restoration, showcasing the iconic Rio Red over a vibrant multi-color interior. It is powered by the prestigious W-series 348-cu.in. V8 equipped with “Tri-Power” induction, a setup that represented the peak of Chevrolet performance in the late fifties. Acquired by the current owner in 1997 and maintained in Venice, Florida, this convertible offers a rare mechanical configuration that combines big-block torque with a date-correct four-speed manual gearbox.
Rio Red Silhouette with Continental Kit and Fender Skirts
The visual character of this 1958 Chevrolet Impala Convertible is defined by its sweeping body lines and elaborate chrome ornamentation. Finished in factory-correct Rio Red during its restoration, the paint remains in good condition, accenting the distinctive triple-unit taillights that became an Impala trademark. The car is equipped with several desirable period accessories, including rear fender skirts and an aftermarket continental kit that extends the rear silhouette. A power-folding white convertible top provides a sharp contrast to the red bodywork and is protected by a matching red parade boot when lowered. The exterior is completed by stock steel wheels wearing correct covers with simulated tri-bar spinners and wrapped in period-accurate reproduction bias-ply whitewall tires.
Red Vinyl and Striped Cloth Cabin with Factory AM Radio
Inside, the cabin has been restored to its original mid-century grandeur, featuring red vinyl upholstery accented by multi-color striped cloth inserts. This complex interior pattern was a hallmark of the first-year Impala, providing a textured, premium feel that separated it from the standard Bel Air models. The dashboard remains in its factory configuration, with the seller reporting no functional issues with the gauges, heater, or the original AM radio. The interior environment is designed for effortless top-down travel, offering enough space for a full parade of passengers. Every detail, from the door panels to the carpeting, reflects the “very well finished” nature of the restoration, maintaining the authentic tactile experience of a 1958 flagship Chevrolet.
Tri Power Super Turbo Thrust V8 and Rare T-10 Manual
Performance is anchored by the 348-cu.in. Super Turbo-Thrust V8, which utilizes a trio of Rochester two-barrel carburetors to produce 280 hp/284 PS and 355 lb-ft/481 Nm of torque. This engine was a significant departure from the small-block V8s of the era, offering the massive low-end grunt required to move the Impala’s substantial frame with authority. While a four-speed manual was not officially on the factory option list until 1959, a date-correct T-10 gearbox has been installed here, reflecting the dealer-installed upgrades available to performance-hungry customers in early 1958. The car is further equipped with power steering and power drum brakes, ensuring the driving experience is refined and manageable. The current owner reports no operational issues with starting or idling, confirming the mechanical integrity of the Tri-Power setup.

First Year Impala Rarity and the Four Speed Advantage
The 1958 Chevrolet Impala Convertible is a stand-alone model in the eyes of collectors, as its specific styling was never repeated. In the current market, 348 Tri-Power cars are considered the “holy grail” of the 1958 production run, often commanding a significant premium over the 283-equipped versions. The addition of a period-correct four-speed manual transmission makes this particular vehicle an outlier, as most Impalas of this era were equipped with the Powerglide automatic or a three-speed manual. This manual configuration transforms the car from a standard boulevard cruiser into a genuine performance machine, benchmarking well against contemporary rivals like the Ford Fairlane 500 Skyliner. For the collector who values mechanical rarity alongside show-quality aesthetics, this Rio Red convertible represents a premier investment.
A Masterfully Preserved 1950s Flagship Cruiser
This 1958 Chevrolet Impala Convertible is a definitive celebration of the Chrome Age, offering a level of presence that few modern vehicles can emulate. From the authoritative bark of its 348 Tri-Power V8 to the sophisticated engagement of its four-speed manual, it provides a visceral connection to Chevrolet’s high-performance heritage. The restoration has aged gracefully under long-term ownership, retaining its “very well finished” status while remaining a turn-key driver. With its clean Florida title and extensive factory literature included, it stands ready for its next chapter. It is a rare opportunity to own a correctly finished, mechanically unique version of the car that started the Impala legend.
