The 3rd generation Chevrolet Caprice is a full sized sedan previously popular in police and taxi markets. It was originally the more luxurious model of the 6th generation Impala until 1986, when it became the base model alongside the 9C1 variant for police and the 9C6 variant for taxi fleets. As a result of the 1977 GM 77 project, the third generation Caprice became shorter and lighter, whilst receiving increased interior space simultaneously. Similar to previous generation models, it was available as a sedan, station wagon, and coupé variant.
