Starting to research what my next car will be. And i'm torn between these two. G37 is more of a luxury/sporty sedan (or coupe). Mustang is American Muscle....and is...well...American. Thoughts? EDIT: I want something with some power. My GF drives an IS350 that I enjoy driving even though it feels cramped inside. I also like the interior of the IS350. Which has steered me toward the G37 which is somewhat comparable. I have also always wanted American Muscle (Camaro, Mustang). Not too hot on the new Camaro and now with the 5.0 in the Mustang, it is getting my attention.
