Describing an FX and EX as a Murano and Rogue makes me wonder if you've driven any of those cars. Especially the Rogue and its CVT, that thing is garbage.
An EX35/37 is literally the exact same car as the G35/G37x with a hatchback, and the FX is about as stiff and quick. And I don't really get why you'd think RWD was necessary? I guess it's just taste, but... Audi? What I wouldn't give to drive this sucker.

Like I said, to each his own, and I've spent a fair number of hours in an early 2000's Mustang, and for me, it wasn't exciting, just felt like driving a car.
