TL vs G35 vs IS300

I will be getting a new car soon and the TL, IS300, and the G35 sedan are my choices. I am going to be posting on all three forums so I can see what everyone has to say. I would also like to know of any problems that the cars may have.

I personally am buying a G35 coupe. I don't really like style of the sedan that much, but I test-drove the coupe and it was awesome. It is just a longer wheelbase Nissan Z with a lot more luxury. So the G35 gets my vote out of the 3.

Yeah every one else seems to be pointing me in that directon also.

IMO IS300 looks the best but I would get a G35 coupe. Why a sedan?

I want some more room and better gas mileage, but performance. I drive a 2002 Mustang GT right now.
