Technically dealers can sell the vehicle ONCE they have the invoice. Until they have the invoice, its not their vehicle to sell and they could possible be breaking state laws or their franchise agreement.
Only problem I see is you are locked into buying the vehicle and if something should happen in transit to you (damage etc), you own it. The dealer is going to demand full payment. Also, the vehicle could be delayed in shipment and it could take a long time to arrive. I know of someone who’s truck has been built 4 weeks ago but it has NOT left the assembly plant yet. They are blaming transportation delays with the Railroads.
