The way it works is that every dealership gets a certain allotment of cars. A waiting list occurs when the dealership has more orders for these cars than it has allotments.
For example, our dealership has no waiting list to order a 2008 Corvette Z06, or C6, but the dealership down the street does. This is because our dealership has a larger allotment of cars than they do. Simple as pie.
So how does this relate to the Camaro? It basically means that if there is a waiting list, there will be no cars on the lot. The only exception would be if a dealership wanted a Camaro to "show", which was not for sale. Otherwise, until the waiting list is tapped out, there will be no Camaros on the lot.
Hope this clears things up.
