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.
'68 428 HO M3 Monster, 4-on-the-floor! Need I say more?
