In my opinion, Nissan will always carry the Scarlet letter of "made with Japanese beer cans.". No matter what will do, it will always be there. Same thing with the Toyota Supr or any other non-German/Italian sports car.
If you would look closer, that is one (if not the main reason) why nissan and Toyota created Lexus and Infinity --- it is all about branding. Oh, don't forget that Honda has Acura!
Mind yah, my Z is a keeper....unless someone wants to trade his Cayenne for mine.
