I would recommend going and driving one TBH. If its anything like the G37 then its in no way a sports car. Depending on what you want that could be exactly what you are looking for, but comparing the G37s to the 370z (which both share the same platform as the 350z/G35), the G felt sluggish and a bit barge like in comparison to the Z. More luxurious though and maybe just what you're after, but dont assume by driving a Z you will get an impression of what the G feels like
