Just for future reference: There's typically a part of the title you tear off and mail to the state when you sign it over. This way you state you sold the car, and whether or not someone else registers it immediately, you are no longer responsible.
It's not like that in every state. I know PA and WV are not like that. You just go to a notary and sign the title over.
