i voted for the G35. it's absolutely gorgeous, has plenty of luxury but is still sporty and quick. the transmission of the one i test drove was silky-smooth, which was nice. 350Z's are nice, but i just prefer the styling of the G35. RX8's are great looking cars and handle extremely well, but they're underpowered. slapping a turbo on a Renesis will give it a lot more power, but it doesn't respond nearly as well to forced induction compared to the 13B-REW because of the exhaust ports. just my $.02.
