Netmag -- you are correct :thumb:!
I just got off the phone w/my dealer (NW Suburbs of Chicago) -- he patiently explained the entire situation to me and said that he would love to put in 1,000 orders for Enclaves but that he would never get them.
I think Axiama's guess is right -- GM is trying to limit allocation to the original dealer allocation (the owner told me some of the ways in which GM measures their business and ultimately uses these measures to mete out "hot" product like the Enclave. One mention was how many days vehicles were in inventory after order -- the quicker they sold something and "turned" it, the more allocation they would get).
So, what I was told is this -- there are 5 orders ahead of me. My order would not likely be entered into the system and picked up for build until September (he essentially guaranteed that it would go in in Sept) -- but said that there was a possibility of it happening in August -- IF (big IF) his allocation increased and/or the 3rd shift goes into operation and makes a noticeable dent in the backlog. He said he'd rather "underpromise" and have us be thrilled w/a quicker delivery vs promise it sooner and then have us pissed off at him, the dealership and Buick if it doesn't arrive for another 4-8 weeks. I also confirmed with him that the orders ahead are simply going to be entered into the system when he has vehicle allocation -- based solely on date -- not on selling price. He said each person worked out their deal with him/them and he wouldn't preference anyone based on anything other than date. He would, however, skip an order if an item would cause a hold on it -- and move to the next order in line so that he could at least get someone a vehicle. When I asked, he said nothing on our order (CXL FWD, 19" Chrome, Ent#4, Towing, Driver Conf, Lux Package -- Platinum/Ebony) would cause a hold. As an example, he said if someone ordered the White Tricoat -- that's on hold -- if he was able to order a vehicle and have it accepted per his allocation, he would move to the next order in line that would allow him to use his allocation slot to get a vehicle built.
Hopefully, this explanation may help others (evidently many of us) in the same spot of me. We're anxiously awaiting ours, but not expecting before November.
