I've been driving nothing but manuals for 35 years. And even though I know that today's auto-manuals are technologically better and faster, I still love the viseral conncection of a manual. With that said, this is the best review and rational for an auto-manual that I've seen or read. It's very well done.
btw, BMW has said that the F10 will be the last M5 offered with a manual, not that the MY2013 would be the last year of an F10 M5 manual. I plan on ordering mine in Sakhir Orange as soon as I can get my hands on the MY2014 LCI!
