An Infinity is as much a Nissan as a Datsun is. A brand name of a manufacturer. A rose by any other name? In the Datsun era, The Nissan badge was reserved for the upper market cars. Then, suddenly, they were all Nissans. Obviously, GM doesn't want to market Cadillacs as Chevrolets. Nissan needed a new upscale brand name as well. The 350Z and the G35 are just variants of the same car, yes? I don't know. How deep does it go? When does the body shell become a G35 or a 350Z. Even further back, in the basic shell component pressings? At the last Turfside show in Escondido, The 350Z and G35 were side by side. My car was about 20 feet from them. I heard many a die hard Z FANATIC walk pass and say "I'd chose the G35". I think if the Central Coast Club excludes a G35, the world would not end. And, vise versa.
