Well would have loved a 350Z but I would rather throw in a turbo on a 8.
Plus point of the RX8 for me: Back seats large enough to fit a car seat. I have a 2 & 1/2 years daughter who is as thrilled about the 8 as I am and loves it. So cant have a car that isn't safe for her as well and the rear doors on the 8 are a stroke of genius 
Besides I love the shape of the 8, have been in love with the curves ever since they launched in 2003.
One last thing is that I can handle the maintenance and fuel of the 8 with ease but cant spend as much money initially as required for the 350Z 
Thanks to every one for their posts guys!
I really appreciate all the help and wisdom that you guys are giving.
