Has anyone out there seen the Millenia SC?  I was wondering if this was what
they were going to do to the Speedster that was shown at the Chicago auto show.
I did manage to get a pretty good look at the SC that was in the speedster.
It was basically a rectangular box with routed grooves to form small heat sink
fins.  Does this fit the description of the SC in the Milenia?
