If I was to buy a RS4 tomorrow it would be the drop top version because

A: I wouldnt take my rs4 on the track other than the ring maybe once or twice driving conservatively (Scared to wreck it). Id buy a Evo for racing.

B: Im a poser. And the RS4 cabriolet is a posers car.

Not too sure if it will sell though as I dont think woman consider the RS4 as pretty.
