The 1958 Impala was the last of Chevrolet's 'tri-Chevys' because of the 1955 to 1958 cars all looking very similar and being an almost identical size. All three were favorites for modifying as they could be ordered with the small-block V8 as standard, and if they had the base straight-six, the larger engine could easily be found second-hand and slotted in. What made the 1958 model most famous was a custom version in the movie American Graffiti, driven by then actor but now famous movie director, Ron Howard. The car shown is typical of the 1960s customs, with the original chrome, a new tube grille, scallop paint work, reversed steel wheels, triple 1959 Cadillac tail lights and a tuck 'n' roll interior. The powerplant is a stroked small-block Chevy with triple carbs which helps the car to 14-second quarter-miles. The Impala gets its low ride through adjustable hydraulic suspension.
