The 1955 Chevy 150 was iconic in American GraffitiBefore George Lucas shocked the world with "Star Wars," he made the 1973 film "American Graffiti." Not only did it earn over $140 million at the box office, but was nominated for five Oscars, including Best Picture and Best Director. The film showcased many of Hollywood's upcoming stars, such as Richard Dreyfuss, Ron Howard, Suzanne Somers, Cindy Williams, Harrison Ford, and yes... the cars.One might jump straight to the yellow deuce coupe (a 1932 Ford Standard), which in the film was "the fastest thing in the valley." We want to highlight the black 1955 Chevy driven by Harrison Ford's character, Bob Falfa, which had a big hood scoop and roll cage. Over the years, it has been mistaken for a Chevrolet 210 and Bel Air, but it's actually a 1955 150 sedan. It's easy to confuse them because all three are basically the same car with different trim packages. The 150 had no side trim, while the 210 only had trim behind the front door. The trim on the top-of-the-line Bel Air stretched from the front fender all the way back to the quarter panel.When the 150s were new, they came with a renovated chassis and Chevy's new small-block V8, producing between 123 and 162 horsepower. Customers could also choose from three different transmissions. Interestingly, Falfa's 150 was one of three initially built for the 1971 film "Two-Lane Blacktop," while a second was used in the crash scene at the end of the film.
