what mustang to get?

I know stick ok... just not like the back of my hand yet and i didn't want to ruin a GT learning and also it's a hassle to drive but I want a GT so bad haha...

So should I just get the fastest regular mustang? This thing is gonna be my baby/toy.. haha

any other cars like a mustang that I should consider?

Not trying to get fucked with by the cops 24/7 but it's kinda worth it haha.
