RUBBERBNDMAN is right. While allocations can sometimes be really specific like "1 allocation for a '09 SRT8 Automatic", ultimately the dealers themselves decide who gets those slots. So for example if you have an R/T Auto on order with a dealer, and they have other R/T Autos being built before yours that are not Sold cars, your dealer is taking you for a ride and trying to maximize their off-the-lot sales since they know you're already committed.
