My husband is buying a used vehicle from a private seller and he is going to have to go out of state to get it. What does he do about the license plate? He thinks he is going to have to get a Florida one and then change it to North Carolina when he gets back. Is there a simpler way to do this?

You should be able to get a 30 day tag or a transporter plate from local dmv

Make sure he gets a bill of sale and insures the car. Most States will allow a drive through with a bill of sale.
