I just got an email survey, the second one from the so called BMW board of drivers - really a flattering name for an email focus group.
This one was focused on the next M3/4 cars, insistently asking if I'd buy one without a manual transmission. Since I've only had manual cars from 1985 onwards, you probably can guess what my answer was.
I told them I'd buy a Porsche if the next M3 doesn't come with a stick, and I told them I'd pay up to $1000 more for a stick - and that's no lie.
Your take may be different, but even if you like your DCT I'd urge you to indicate an interest for manual, in case BMW asks. Won't hurt the DCT none, and it may help the rest of us to stave off the inevitable for at least one more generation.
