f5fstop, thanks! That clears up A LOT of things!
Here is one more for you on this subject if you don't mind!? I have read on a few other sites that when a Dealership honors / accepts a GMID and sells the vehicle at the GMID price that they get reimbursed by GM for that deal since they had the potential of making a lot more on the vehicle if it were sold to someone that was not eligible for the discount. If this is true, can you post details on how that works? Is it a certain %, a flat $ amount, etc etc
