The Chevrolet Impala was introduced in 1958 and positioned as Chevrolet's mid-priced vehicle. It was built on Chevy's new 'Safety Girder' X-type frame and was the basis for a longer, lower and wider body that reduced overall height without compromising passenger headroom. Other features included a full coil-spring suspension system, a foot-operated parking brake, and anti-dive braking.
The Impala was given quad headlamps. The Sport Convertible and the two-door Hardtop Sport Coupe models were the top-line models in the Chevrolet's Bel Air Series. They came equipped with all the trim and features of the lesser models, plus Impala-specific scripts, insignia, checkered flag emblems, ribbed body sill panels, imitation chrome scoops ahead of the rear wheels, a two-spoke deep-dish steering wheel, a rear radio speaker grille, and triple rear taillights.
This 1958 Chevrolet Impala Convertible is painted in correct Cay Coral exterior color with coral seats and carpeting. Power is from the optional 348 cubic-inch 'Turbo-Thrust' engine that offers 250 horsepower. There is a two-speed Powerglide automatic transmission, and four-wheel hydraulic drum brakes. It has power steering, power brakes, power windows, an AM radio with a rear speaker, dual rear antennas, an electric clock, a day/night mirror, and air conditioning. There is also a factory-installed Continental kit.
In 2009, this Impala Sport Convertible was offered for sale at the Automobiles of Arizona auction presented by RM Auctions. It was estimated to sell for $90,000 - $110,000. The lot was sold for the sum of $93,500 including buyer's premium.
