If you haven't done this before it takes about 6 weeks longer.
I was about to do the same thing. Then I realized you have to wait on the transfer from one dealer to the other. Then you do the form 4 stuff with the local dealer. It was worth paying $60 more for me to get it 6 weeks sooner.
This is just the info I was told, cant attest to it other than I heard directly from the vendor I was looking to purchase from. May make a phone call to confirm.. Save you some headache and time.
