Just saw this episode of Drive where they reviewed some of the most outrageous options offered by auto manufacturers. I can't believe that you can actually option a base 3 series to be more expensive than an M3!!!
If you think BMW is bad watch the whole video
What option(s) did you get on your Bimmer that you later regretted? Or conversely, what option(s) didn't you get that you later wish you had?
