It takes time for the trackers to catch up. Ask him for a copy of the VVR, which is the most up to date. Otherwise, sooner or later the trackers will catch up.
They go into production when the window sticker is made (or vise versa), about 6-8 days prior to your build date. Mine went into production on 9/7, window sticker available that evening. It was built yesterday, with a confirmation email overnight that it was built. Ordered on June 3, while I got the VIN and build week on August 12
