Summit White is scheduled to start production in July 2009...a date which has not shifted since October 2008 announcements. Date recently confirmed by a dealer member of Camaro5 in a PM. Order system should open for Summit White around June 15 to allow for orders to be pulled for production post-July 13 when the plant reopens after shutdown for model changeover.
