Yesterday I got the pleasure of zipping around Tampa in my Red Z with the tops out an my Santa hat and shades on. I know it adds weight to an already heavy car, but all I've seen on the 350Z's are slick tops.... not even a moonroof (maybe they exist, I don't know). This may change on future 350's, but for now I still favor the smoother lines, the wrap-around dash, and the t-tops of my 300. At Stage 4+, I'd probably give a new 350 a hell of a run for its money. If buying new, I'd opt for the G35 Coupe. Just my $0.02. Happy Holiday's all.
