CCS is the place to go if you want to do trans. Art Center is great but they just teach you the fluffy stuff. Also, I've heard the auto companies are actually hiring product designers to get a different interpetation of the automobile form.
If she does go into transportation design she should expect to be designing only small components (knobs, door handles) for the first couple years or even just working CAD. The interior and body development is reserved for the more senior designers. Also, salary for a trans designer is pretty craptastic at first.
Check these portoflios out. She needs to bench mark off of these guys.

If you have any questions just post it up. I went to school for industrial design and was strongly considering transportation design but the negatives outweighed the coolness of the profession for me.
