That's a good question. It really depends on the condition of the incentives availabe at the time you are taking delivery of the car.

For instance, in the past there were incentives where they were only for vehicles in dealer stock. Thus no incentive on ordered ars most likely meant over invoice pricing. But this latest premium package credit is available for all cars that are sold during when the incentive is being offered; thus under invoice pricing is possible on ordered cars also (mine was ordered originally slightly above invoice, but I was fortunate enough to take delivery of the car when the incentive was offered and got under invoice pricing).

Not sure if the incentives are lockable like the lease/financing special rates. I'd go ask your Client Advisor for that info.
