When Chevrolet revealed the Caprice in late 1965 as a 1966 car, nobody expected it would be so successful. In fact, it went on to span five generations, selling millions of cars. They designed the Caprice as a luxury version of the Impala with more powerful engines, luxury and a few distinctive external differences. For example, in the 1966 model, the base engine was a V8, not a straight six. Also, all models had a vinyl roof as standard. And for performance lovers, Chevrolet offered the 396 and 400 V8 engines in the Caprice four-door hardtop.
