i ordered mine through the gm supplier website for the discount, and was paying cash. When it came in the dealer called me to tell me I had a vehicle ready for pickup and was not happy about selling it at the discount price. Kept talking about they could get 80k+ at auction and I told them it wasn't my problem, I was the only authorized purchaser of that vehicle and at the price it was when I ordered it. I tried to work with them and told them I'd finance at the 0% offered but they refused because I was already getting the supplier discount. Can't stand shady dealers, and what makes matters worse is I plan on buying a C8 at some point in the near future, but will not be going through that dealership.I paid mine cash, salesman and finance manager were pissed. They didn't want to sell me the vehicle. Salesman came with a 4k markup when we had agreed to msrp minus incentives. I highlighted all the B.S. junk they were adding as they did bring me a itemized deal list and had them cross out all items i was not going to pay for, i didn't even pay for the 3yr mandatory onstar subscription which btw is 1500 usd. Ended up paying 4k below MSRP.
