That's what I did with mine. Temp plate taped to the rear window. They took my check, I drove the Volt home. In states where a front plate is required the dealer typically will add the mount if it's not already there. But that will not prevent the car from being legal on the road while a temp plate is on it.Usually you drive the car home. All it takes is a document taped to the front windshield to make it legal. I suppose there is some kind of prep work that needs to be done but the license plate holder is not a show stopper and the plates are sent in the mail from the DMV.
