This is too hard.
BOSS Mustang. Pre-’69. ‘69+ too long and fat and not enough angles.
Park it next to the other guy’s 63 GTO.
The first Boss Mustangs were ‘69. Boss 302 and 429. Boss 351 was 71.
The big oversized Mustangs were the 71-73. My least favorite of the original generation. Never liked the appearance of the hood going all the way up to the windshield. They did away with the vented cowl in 71. It just looks cheap to me.
If I could pick one car for my dream it would be a ‘68 Shelby GT500KR convertible. Red with tan interior and the 4 speed.
That’s, in my mind, a pony car, not a muscle car. For a muscle car I’d take a ‘66 Fairlane HT with a big block FE and the 4 Speed.
