going through this myself. during hours that the dmv is open, you can drive from the place of purchase to the nearest dmv if you have the title, bill of sale and insurance on you. after hours, weekends and holidays, you can drive the car all you want (with that stuff in the car), until the next opening hours of the dmv.
you can get temp plates with the title, bill of sale and insurance.
all of this info is on the interwebs if you google it.
