1958 Chevrolet Impala Convertible

This 1958 Chevrolet Impala Convertible is a striking example of one of the most recognizable designs of the postwar era. Its one-year-only body styling sets it apart from every Chevrolet before or after it. Impala convertibles made up fewer than 5% of all 1958 Chevrolet production, and far fewer survive nearly 70 years later. Under the hood, the optional and correct W-Code 348 Turbo-Thrust V8 breathes through three two-barrel carburetors, sending power through a correct Powerglide 2-speed automatic. This car offers rarity, presence, and real collector value in one package.

The 1958 model year marked a bold turning point for Chevrolet. The Impala debuted as the top-of-the-line Bel Air series, offered only as a sport coupe and convertible. That same year, Chevrolet launched the new 348 “W” big-block, named for its distinctive valve-cover profile. It also introduced a new X-frame chassis, full coil-spring suspension, and quad headlights. For 1959, Chevrolet redesigned the car completely, so the sculpted lines, rear fender scoops, and triple taillights you see here belong to 1958 alone.
