They have the same information that was posted in a closed thread, and people found that amazing. When someone looks at that same info on a computer and puts it into words, it becomes useless.
Either way, this is what Chevy has stated for obtaining order information - use it as you will. But as I posted above, YOUR DEALER is your number 1 source. They will see it move through the sysytem, and they will see a build date. Good dealers will keep an eye on this and let you know when things change - because the good dealers know what this car means to you. I know at least TWO such dealers here that do that, I'm sure there's more.
