CONGRATS! The anticipation when ordering is horrible but well worth the wait as you're only paying for what you want and getting exactly what you want.
Just keep in mind the initial 1,200 mi break-in period/ RPM limits and subsequent service for the M models. You're jaunt through the mountains should be perfect, though (Tail of the dragon would probably be the best way ever to break in a new M!)
Find out your production number from either the owner's circle or (probably easier) to get from your SA. Then, go to the M3 Pricing, Ordering, Tracking section of M3post and look for a thread with your vessel name to share the anxiety with other forum members on the same ship that yours is on. LOL If you don't see one, go to the same section over on e90post.com 3 Series forum (HERE)
. If you still don't find one, go ahead an create a new thread and otehrs will chime in soon enough. GL
