I came across the Saris site last evening. They claim they can fit any car, however, there is still no Smart listed on their site..... might have to give them sometime.
I did run across another site where a Smart owner had a hook on bike rack and I sent.... or tried to send him/her a message but yet no answer. The local bike shop is a Saris dealer so I'll try to get down there and check things out.
If someone else comes up with something.... please post. I have a Cabrio so I'm somewhat limited on what to use.... plus I'm somewhat concerned about what the bike and rack will do to gas mileage on a long haul somewhere. (I'm traveling from Southern Cal. to Kansas next month and would really like to take the bike & my fortwo.)
Best wishes,
Steve
