The last of the true dinosaur sized Chevrolet Impalas, this 1976 model two door fastback was downsized in 1977 model to meet pollution and mileage standards set by the Federal Government. My first car was a 1968 Impala I bought in 1974 and it was smaller, not by much, than this model. Unfortunately, GM has killed off the Impala. It was the number one seller in the USA back in the 60's when you could get a roomy car without paying the price of a Cadillac for example.
