On the plus side, it appears that from here on in Pontiac will be publishing "Target Production Weeks" for the Solstice. That will also lead to "Estimated Delivery Dates" being available.
Also there is the experience that every one has gained on understanding allocations, order cyles, and constraints.
One possible minus, could be the allocation process. If it goes to "Turn and Earn", it could hurt smaller dealerships or dealers with cars in inventory. It also could eliminate the dealerships being given allocation quanitites in large segments, ie the "four month" amounts we have seen this year.
