In 1964 very little changed in the Impala line. The new body style lead to a more rounded softer look. The big full size Impala line was once again being marketed as "Jet Smooth!" The roof line for 1964 was the same as it had been for 1963. In 1964 you could order a vinyl top option (RPO C08) on any solid exterior color sport coupe. Combined with the ribbed roofline styling this option made the sport coupe look very much like a convertible. The "SS" Impala continued to feature the engine-turned swirl pattern aluminum trim. The Impala four-door sedan remained the mainstay of the Impala line.1964 Impala production was 889,000 units with 185,523 of those being the Super Sport Impalas. It didn't happen often but the Impala or the Impala Super Sport could be ordered with the standard 6-cylinder engine.
