The number won't mean much at this point, it's more about the options the particular car has. The only site that lists a collection of cars and allocations available is Ebay. Unless you want to do the legwork yourself and call around to dealers to see if they would have anything available for 2016..
R allocations will be very difficult to find since Ford won't be releasing any more until March.
