I prefer manual, but unfortunately, use my car to commute. Traffic being as bad as it is in the DC area, it would be a pain to drive stick. I do wish I had stick when there is a stretch of no traffic though, as the auto trannies suck, even in the "manual" mode.
Most people buy BMWs for one of two reasons:
1. they like to drive - small group that actually would buy manual, probably majority of members here
2. they just want to say they own a BMW, but can careless about performance - probably majority of BMW owners and (me being one exception), most people that get auto trannies, because they can't drive stick.
