What's the deal with the Z51? I can't believe it's so hard to buy this car. My dealer is trying to get me to buy a 1LT but that's not what I want. He told me they try to put in a order for a Z51 but the system wouldn't let him. This dealer get a lot of the Stingrays but they are telling me that no one is really able to order them rite now how true is this, and what can I do I want the car.
