Vehicle registration?

I bought a suv from a dealer (ford) my paper registration goes up today. They just now text me. Text not call, telling me "
So the gentleman from our registration department told me to finish the registration process he needs to do a quick VIN inspection. It only tak es a couple minutes the said. Can you bring the vehicle in today? If so what time?" The thing is I'm out of town. Even then how long till I get my license plate. So far this has been a horrible experience for me. Told me the suv only had two owners only two dents nothing hardcore. Which I saw and got them out easy. However my back window does not roll up found that out a few days later, how buying it.

I was just wondering what could happen to me if I get pulled over, of there's anything I can do to help me out etc…
