He told me once your order is the GM Workbench , it's technically a "placed" order. (Yes, it's only status 1100, so, it's not going anywhere), but he told me, many customers waiting for their allocation will change their minds hundreds of times on options, trim, and colors. Each time you change your mind, a salesperson has to go into workbench and make those changes.
Yes, Murray, that is somewhat "self serving", but I get that and he was open and honest about the reasoning. I didn't have a problem with it, and I too have changed my mind several times over the last few months. (Went from a 1LT coupe in Rapid Blue to now, a 2LT Z51 in Torch Red. 
).
Like I said, Andrew did say he would enter the order right away if I really wanted, but experience has told them it was best to wait until we got a few weeks back from my allocation. They're a smaller (staff wise) dealership, and they fully cater to their Corvette clientele, however, as we always said in the military, "work smarter, not harder".
Regardless, I'm not concerned at all, and each month Andrew has emailed me an updated status on my place in line.
