Smh... bottom line is the current mustang handles pretty good. When the coyote stang debuted in 2011, it held its own against the excellent M3 on the track. Its only gotten better since.
I could be wrong... I myself am far from perfect, but I got the vibe that you’re knowledge on cars, specially various platforms is lacking. That would probably explain the mis info you have on the mustang. This is just from various posts Ive seen from you on the forums.
In relation to bikes, that is probably you’re jam and I have much to learn in that regard. Good day.
