Sounds like you have a good group of cars Mecinoid.
If you want a 2013 ZL1 you need to ask some important questions first. You should be talking with the inventory director or sales manager. Ask 1) Do you have a 2013 allocation. 2) How many allocations do you have. 3) How many allocations have been used. 4) Do you have the production cycle and when will my order be submitted. You will not receive an order # until the order is accepted by Chevy for production. From that time it will be at least 6 weeks until you get your car. Mine (2012) was ordered Feb 1st and I don't have an order # yet. I feel the wait will be worth it.
