The Impala has been one of the most popular cars in the United States since Chevrolet introduced it in 1958. It was designed to be a luxury car that average people could afford. It is available as a four-door sedan, a two-door coupe, or a two-door convertible. Early models had distinct symmetrical triple taillights. The updated 1959 Impala had an eight-cylinder engine, large single taillights, outward facing rear fins, and an optional power driver's seat. The 1960 Impala even had optional cruise control, the first time this feature was offered on a less expensive car. The updated 1964 Impala was smaller, with a more rounded, aerodynamic look. The Impala Caprice, introduced in 1965, was only available as a four-door hardtop. It had very plush upholstery, wood grain accents on the dashboard, and special interior door handles. Since it was so successful, Chevrolet made the Caprice a separate line of cars in 1966. You can use the reliable sellers on eBay to find the perfect vintage Impala or a new model with lots of luxury features.
