I went to a BMW dealer yesterday and I noticed that the 323Ci that I was looking at had a short (about 3" or so) funny shaped black antenna. I did not particularly care for the way it looked. I have seen pictures of E46's that have the antenna and some that don't. For instance in the BMW 3 Series sedan book none of the cars seem to have the antenna. (Of course all the cars in the book are sedans not coupes.) I was just wondering if this antenna is the BMW standard on the coupe or sedan or if it some sort of dealer installed option.
