The Impala may be the quintessential American car. Few cars have the production numbers or status of the 64 Impala. The Impala appeared first as an upper trim package on the 1958 model to becoming its own top model the following year. The performance oriented Impala SS became the top model in 1961 packing the famous 409 V8 as the top engine. The Impala SS was later replaced by the Caprice as the top model but the Impala name has continued to be the most fondly remembered of the Chevy full size cars. Today the Impala is still the top line Chevrolet car. Checkout our full list of Chevrolet Impala parts for most model years!
