Good luck with the Bimmer! As a past owner of 5 Bimmers (2 M's), and a current owner of one, I will take my Z over them all anyday
However, I did miss them, so got my current one to go with the Z.
They are expensive to maintain, unless you are a DIY kind of person. Look up indy shops there in Hono called A&A Motor Werkes and german Auto Specialist. Great shops!
Oh, and juice box that bad boy and have some fun!
