I have nothing but good stuff to say about the RS series. The good thing was that there were only a 1000 imported into the US (from the article). BUT, body parts like the fenders will be incredibly rare, hard to get and it will also be fantastically expensive to maintain compared to the 330i (which prob costs you nothing).
You haven't talked much about your requirements or the budget so i cannot really recommend anything other than warn you about debt inducing servicing.
