Question - Buying a car from WI

[CVD]

When I bought a car out of state I worked it out to mail his plates back to him. I think you'd be fine with no plates though. If you put your own plate from a different car on there and a cop runs it and it doesn't match they're going to think the car/plates were stolen. They'll probably let you go but you might get pulled over by about 4 squads and fuck around on the side of the freeway for half an hour depending on the cop.
