Much like the Ford GT supercar that came before it, the Ford Mustang GTD is being sold with a big caveat. The automaker has confirmed new owners must agree not to sell their car within the first two years of ownership. This sort of rule is meant to prevent Ford's new mega-Mustang from being immediately flipped for a massive profit.

Ford's GTD monster Mustang isn't just a performance heavyweight; it's going to be an actual heavyweight. EPA documents show that the new fastest Mustang is going to be a lot heftier than we expected from any pony car.
