I agree with you totally. I think the OE mirrors tend to look bulky and cheap. Somebody could do the S197 world a real favor, and make some $, if they offered an easily swapped, smaller and better looking mirror.
The current mirror could look a lot better if it was painted body color. I think the clip-on body color covers that are sold look bad, IMHO, because they cover only a portion of the mirror and ultimately make it look worse.
There are a lot more important things in life to worry about

, but another option for mirrors would indeed be nice.
