In 1965, Chevrolet introduced the Impala SS convertible. The SS, or Super Sport, was a performance package that added larger brakes, a stronger suspension, and chrome trim. The convertible was the top-of-the-line Impala, and it came with a powerful V8 engine. Today, the 1965 Chevrolet Impala SS Convertible is a highly sought-after collector's car. It's not only beautiful but also rare; only about 4,000 were made in 1965. With its sleek lines and powerful engine, the Impala SS convertible is an iconic American muscle car.
