The 1967 Chevrolet Impala SS427 Convertible stands as a rare and unforgettable icon in American muscle car history. This particular example, a verified one-of-one, boasts an extraordinary backstory, factory customizations, and a carefully documented lineage that sets it apart from any other. Originally ordered by the vice president of Chevrolet for his wife, the car blends luxury, style, and raw performance into a uniquely compelling package. With its white exterior and bright blue interior, this convertible is a bold visual statement, made even more significant by its Berger Chevrolet legacy.
Unique origin and history: The story begins with a personal order from Chevrolet’s executive office, specifying uncommon factory options such as Comfortron air conditioning, factory side accent stripes, wood-grain steering wheel, and a distinctive 3-note horn. After a brief period in the executive’s family, the car was listed for sale through Chevrolet’s internal network. Dale Berger Jr. of Berger Chevrolet in Grand Rapids recognized its value and acquired the vehicle. Under his ownership, the car received performance-themed cosmetic upgrades, including 427 badging on the domed hood and trunk, as well as long chrome exhaust pipes replacing the rear resonators.
Engine and performance specs: Powering this Impala is a rebuilt 427-cubic inch V8 producing 385 horsepower. The restoration included a complete nut-and-bolt frame-off rebuild, preserving the engine’s authentic character. Mated to the original, untouched Turbo-Hydramatic 400 automatic transmission, the drivetrain retains factory reliability and strong muscle car credentials. The car’s original air-conditioning compressor and radiator have also been maintained, further attesting to the preservation quality. Combined with performance exhaust modifications and Corvette-style 15×8 Rally wheels, this SS427 offers both visual flair and period-correct muscle.
Exterior and styling highlights: The white paintwork accentuated with factory-correct side accent stripes presents a clean and authoritative stance. Only 200 of the 1967 Impala convertibles featured these stripes, making this car even more exclusive. The Corvette rally wheels, sourced in 1969 and fitted with the correct beauty rings, add a sporty, aggressive stance. Chrome details throughout, from the bumper trim to the upgraded exhaust tips, provide a fitting touch to the convertible’s grand touring aesthetic.
Interior features and condition: Inside, the bright blue vinyl upholstery gives a vivid contrast to the car’s exterior and adds a vibrant, upscale appeal. The interior reflects the same meticulous attention to restoration as the mechanicals, with original appointments retained and restored wherever possible. The wood-grain steering wheel and period radio enhance the driving ambiance, while factory comfort features like Comfortron air make cruising a refined experience.
Legacy and rarity: Out of 128 Impala SS427 convertibles built for 1967, very few survive with such unique provenance and restoration quality. The Berger name alone adds a layer of performance credibility, especially considering the dealership’s iconic status in Chevrolet performance history. Combined with the personal connection to GM leadership, this car is far more than just a rare build—it’s a museum-worthy piece of American automotive history.
Ownership and preservation: Showing approximately 80,000 miles, this Impala has been restored and preserved with collector-level attention. With a clear trail from executive ownership to Berger Chevrolet and through a professional restoration, its pedigree is fully documented. This one-of-a-kind Impala SS427 isn’t merely a showpiece—it represents a unique intersection of corporate heritage, performance culture, and timeless design.
