30. Chevrolet Chevelle SS
The mighty LS6 engine was gone for 1971 but car buyers still got the LS5 454 V8 they rated at 365 HP. And that was still more than enough to post respectable quarter-mile times. From the outside, the Chevelle retained the same look.
But Chevy gave it a different front grille with two instead of four headlights and a different rear bumper. Arguably, the 1970 model looked better than the 1971 or 1972 renditions.
