I would make sure that no one from the dealership takes your new beauty for a joy ride before you get it. I have seen it happen to others and demand that I watch my car come off the car hauler if at all possible. We all love the Vette new Z's and can't wait to drive them, so just imagine how many people at the dealership would jump at any opportunity to run one at WOT for a little bit BEFORE you get it broken in properly. Hopefully your dealership is among the many that are respectable and won't do that, but just be cautious.
