SL/R230: Don't laugh....do any bike racks fit the SL?

everybody thought i was just 'trying to look cool' by asking, but it would have been nice. i ended up driving home with the top down and my girlfriend's new bike on the passenger seat one day. it was ridiculous.
anyway, i didn't have any luck and i don't have the MB option. I think that option includes small rectangle receiver slots on the sides of the roof over the windows. if you don't have those, you don't have the option (unless i'm mistaken)
good luck though. if you find any, let me know.
