i think this bike would fit without folding:

sorry.

but on a serious note, the big boys like yakima and thule don't make a carrier that fits a crossfire at this time. i'm not sure the roof is big enough to provide stability to bicycles mounted above. it might be hard to have a rack on the rear of the car as well since it might interfere with the spoiler movement. if the crossfire had a hitch receptacle, or can be modified to have one, it might be doable. but then the visibility through the rear window would be further reduced.
