Looks like I split the difference! I pick up @ 3:40. I'll have the Space Grey M3 sedan with the ZCP package. Sounds like I'll see you on the tour and and the lounge. Can't believe it is coming up so soon now.
Also I did find out the tires don't look to be a issue. BMW recommends them on 10/15 but the law is only comes in play if you are found to be driving in snow or ice with summer tires. I want to avoid those conditions for a host of reasons. A little research sowed that Munich is typically in the low 50's in the latter part of October so I don't think it is much of a gamble. I can always have them put on if the forecast is bad when I arrive.
