I'd say it was 67...the Chevy II.
After that, everything had to get huge for some reason, Camaros, Mustangs, muscle cars. They became sedan-sized platforms with "sporty looking" body styles.
Yes but but 67 brought all the big motors to the Nova and cheaper than the Boo or Chevelle
But you’re right a 65/66 Nova was small and lighter and with that 327/350 motor was a Goat grabber in sheeps clothing
Alas my folks wouldn’t allow me to buy a power car when I came of age in 72
Hence an MGBGT
Now I get tempted on occasion
Last week I looked at a 70 Dodge Dart 340 Swinger
Non numbers fairly cheap
My wife rolls her eyes I’m being silly
