Be honest with yourself, if you compromise and get the white, will you be happy or will you feel a pang of regret everytime a black nismo drives by. If you do/will, then wait and get exactly what you want. If you can live with the white, then just get the white.
Me personally, I would rather wait and get exactly what I want and have no regrets/compromises vs. immediate gratification.
