because some people still do prefer a NA engine over a FI induction engine (myself included).
if I had the money to choose between a 335i or an M3, I go M3 all day everyday. So what if a 335i with small mod can take me.
If I can afford an M3, I can not only afford the gas and, reasonably speaking, I can afford the mods to it to make it go even faster. This is of course I am going in with the mind set to mod the car.
