I admit I forgot about the GTD, but it’s not immediately clear to me if that’s truly a factory vehicle. I detailed it (way too much) in my reply to your comment’s reply. The GTD gets shipped to a second facility to get finished as a GTD. So if it’s all Ford, then yes, it should count, as long as it’s still meeting production-vehicle definitions. If it changes hands to a 3rd party as a complete vehicld, it’s then not a factory vehicle, in the same way a Roush Mustang gets shipped as a complete factory Mustang to Roush, gets modified, then shipped onward to a dealer, still as a new car.
To clarify the Shelby site linked by the other comment, some of those are definitely licensed kit upfits, though I believe all in that site are such. None are actually Ford-produced.
