One such is the California Special package, which has been one of the
favorite trims for Mustang lovers everywhere. The full breadth of
details surrounding the 2013 Mustang California Special have yet to be
announced, but it appears that it will carry a number of unique
additions similar to what Ford did with the 2012 version.

Among the noticeable modifications given to the 2013 Mustang California
Special will include a unique front grille, side scoops, a new pedestal
rear wing, a new rear diffuser, special black decals on the hood and
side of the car, and just like the 2012 model, a special interior trim.
