Damn you're tall! Lol. I'm pretty certain that you would fit but I am not too sure how comfortable it would for you, especially if you are planning long trips. Best bet would be to find one for sale somewhere near you and see if you can have a seat in it. But as far as fitting, yes im sure you can, the seat goes back pretty far on the 99+. For a sports car, mustangs are pretty user-convenient and comfortable. Anyway, hope my input helped.
