G37X with some OEM optional 18" rims like above would be perfect. I personally prefer the post-facelift ones but the pre-facelift ones are good too. The thing with late model G35s is that they're down about 30 horsepower and a few MPG from the G37 and have a 5 speed auto rather than the 7 speed. Plus, the used ones around me are all similarly priced so you might as well get the G37 anyways. In the comments I'll post a link to a clean title pre-facelift G37X I'm watching with 137k miles for only $5k.
