I am wondering how BMW chooses the names for the different series. 323 vs. 328 vs. 330 makes sense but I am wondering about the letters that follow... I have seen older 3-series coupes with an "is" (liki 323is) on the back. I have leared that means "sport" but then how does that differ from the sporting packages that are offered on the new 3-series. In other words, why not call a new coupe (with sports package) a 323csi? I know that is stretching it... the 635csi was one of my favorite bimmers so that is why I ask.
Does anyone know how BMW chooses these codes. Why all of a sudden include the "c" for the coupes when was only used previously on the 8-series.
Thanks in advance....
