I don't buy the basic premiss. Sure, initial production allocation and orders have been tight and with ~900 dealers getting allocation, all wanting to cash in on the $6000 margin gravy train called the C7 you are bound to hear a salesman or manager talk all day about how scarce and "limited" the production is. From their perspective, knowing they will only get maybe 5 C7's for the entire model year it certainly seems that way to them. The reality is GM hopes to sell over 30,000 C7's in the 2014 model year. To accomplish that they will need to release a lot more than they have in the current, initial allocation. Already dealers like Hendrick have booked 15+ vehicles from their initial allocation as "dealer stock" so even with allocation lower than say Kerbek or Coughlin they have exhausted "pre-orders".
I've seen this type of hype for every new model performance car for decades, FUD runs rampant. Explain how, with such a massive wait list expected, that a customer with a delayed order already placed at one dealer is able to initiate a new order with a volume dealer Monday of this week, will have it built before the end of the month and probably take delivery mid November?
My prediction, using only experience I have from past events like this, is by spring of next year volume dealers will have vehicle in stock. There will be no more second stickers, cars will sell for MSRP or less and by the end of the model run or perhaps initiated with the 2015 model run, employee and supplier pricing will be honored.
