I use "ZH" simply because it has a nice BITE to it aside from the fact that "Crossfire" is the retail name for the car and "ZH" is the engineering name (me beinging a auto automation engineering). I dig the engineering end of the Crossfire and its story how the Crossfire angered the Germans to the point they refused to sell the 2007 in Eroupe for over a year.

The Crossfire was the car that broke the Germans back in the whole Chrysler/Diamler relationship. The story is rich and Diamler never got over the fact the world chose the Crossfire over the SLK (to this day).
