They look the same. My freind has a Cobra and the mustang has that same Z roof line as the Z. Remember, Ford used to own part of Nissan. I.E. mercury Villager/Quest on the old Maxima chassis and engine.Who's to know how much technology Ford aquired from Nissan when they owned part of them. But the Z and the new chassis Mustangs look alot alike on the roof line. I'm curios about the SVT independent rear suspension on the Stangs also. Never seen one but is it like the Z's? Paul
