I think that a definite car "culture" exists in Southern California, and I think that Nissan and many other makes either consciously or subconsiously benefit from this culture...though not all of them, i.e. Lincoln/Mercury..for whatever reason. And, like it or not, for better or for worse, the huge metropolitain area that makes up the Southern California skews toward import car buyers. And, a lot of the country follows trends that are set in Southern California.
So, I think that Nissan is rocking the boat on this...certain industries benefit from being in areas that have a balance of the culture that impacts their core business, othere similar members of their industry, and the talent pool for staffing...I think that if Warner Brothers were to move from Hollywood to say, Omaha, it might end up being very problematic for them to find the same overall balance that they have access to now in the middle of Hollywood...even though Omaha might prove cheaper for them to operate in. Yes, I know other car companies are setting up shop in other "non car" pockets of the country outside of Detroit and Southern California..but unless memory fails me, these were new operations that I do not think resulted in the move of the core organization the way that Nissan is planning to do. At any rate, I cannot help but feel that Nissan is playing with fire on this one...I hope I am wrong...who knows, maybe it is a brilliant strategy, and GM will end up moving everybody to Provo, Utah.
