This one is very close, but I'm going with the Camaro because it is a Yenko and because '69 is my favorite Camaro. The Mustang is a close second, mainly because of its styling and 'Cuda is a very respectable third; not quite as well styled as the other two but a powerhouse.
John, when I saw today's poll, I was expecting to see cars that look like this:
full-size; Plymouth run away, Ford & Chevy tie.
'69 Mustang #1 + '68 my favorite years; Camaro #2 but my favorite year Camaro; Plymouth #3 in '60's, but in '71 my favorite pony car the Cuda. Keep going: 1970 Favorite pony car the Challenger T/A & my favorite Javelin/AMX 1970 & Pontiac Trans Am 1977 & '78 & Cougar '67 &'68.
For the first group of 69's from John. The fastback Barracuda first, then the Camaro and last the Mustang. Pete's grouping I go with the Chevrolet first, Plymouth 2nd, and then the Ford.
