Best muscle era design year?

Actually it is a "Chrysler" poll. But the other manufacturers are also very close to same year ranges. But for entirely different reasons. The Corvette folks? It's '63 and '67. Hands down. Camaro/Mustang? '69. GM A-bodies? (Their mid size models) Chevelle, GTO, 442, GS is a whole other discussion.
Definitely 67 for the Vette. Guy across the street from me when I was a kid had a buddy with a black 67 Corvette convertible with the 427, rally wheels and factory side pipes and it was parked in front of my house regularly. He also had a friend with a 70 Lime green Road Runner that had a full length picture of the road runner on the side. Not to mention his own cars 67 Buick GS, then a 71 Charger R/T and last but not least a 70 SS 454 WS6. Cranberry red, black stripes with a tan interior. Oh, and it was a 4-speed. That one he kept... still had it when I left for school in 79.
