Thank you Tomko for giving us at least a tentative target date; while we all know that everything GM is subject to change at will, thanks for at least venturing a target date.
Of course with the usual new model/model year at least two week quality hold, I am going to envision the first ones will arrive at dealers around September 1st -- again knowing that my guesstimate is just that, and of course subject to wild date swings....
