You can also have the dealer do a 'search'. They have access to other dealer's inventory and can trade vehicles to get the one you want.

When I bought my truck, the dealer did a 3 way trade - sent a vehicle to one dealer, who sent another vehcile to another dealer, who sent my truck to my dealer. When I bought my wife's Taurus, my dealer traded a dealer in Ohio a SuperDuty for the Taurus.
