I have 71 plates on my Challenger. A few years back I drove my Challenger one clean Feb morning. As I was just about to leave my neighborhood 2 police cars hemmed me in and drew their guns on me. Told me to open my briefcase that was on the floor. I asked what the hell that was all about. They said "no one would be driving a car like this in the middle of winter!" Funny now. Not then. Oh and they said the number on my 71 plates were registered to a Honda. I have the paperwork you have to keep in the glovebox to SHOW that they are legit old plates registered to your vehicle.
