Let's talk about a Chevrolet. And start with the Impala. That's the beauty I found for https://giantclassiccars.com/chevrolet/394942-1967-chevrolet-impala-supernatural-clone.html The design of the 1967 model was changed in accordance with the 1963 Buick Riviera design. In the back, the shape of the “cola bottle” “strengthened”, and such bends as in the models of 1967-1968. the Impala never had again. And the chrome on all subsequent models was much less than in 1967. The 1967 model was produced in 6 variations: 2-door convertible (open top), 2-door coupe, 2-door hardtop, 4-door hardtop, 4-door sedan, 4-door station wagon. Of these, the most common were 2-coupe and 2-hardtop, but four-door sold out well, mainly as a "family car".
