You guys are all bought out by a 40-year old bogus line. The term Pony was thought up by Ford geeks to create a class they thought they could control. Just like the horse itself.
Goobers and geeks allowed the phrase and the thought-process to gain ground and eventually become a market standard.
My 68 bird is not in the pony class or category, and it never was. Okay, I can see the Cougar being thrown in there, but not my monster Firebird.
I am not going down on this non-industry-standard bullcrap category, originated by Ford.
AND the Mustang was actually NOT named after the horse, it was to be named after the Mustang airplane!! Fords marketing dept screwed it up and came out with a horse!
So plane= birds! Birds it is! pony style birds...lol
