I also have three links set up at
www.trackengine.com (for BMW home page, X6m Product Page, and X6m Build page) to be checked daily for any web site changes.
TrackEngine will check these pages once a day and send me an email if anything changes on them. Particularly, I want to know when the "2012" on the build pages changes to "2013" as that will indicate public notice of the pricing/option changes and availability. When that happens, we should be fairly close...
