Shop manuals?

I have been looking high and low to find a source for the official BMW published shop manual for a 2002 330xi.

However, I haven't been overly successful. Does BMW not sell their factory service manuals?

If not, is the best resource for repair information for a 3-series really the Bentley publishers book?

Thanks
Patrick

no they dont sell them as far as i know the only source to techs is over their network.
