Michigan is a Both state also. On my registration it is listed as a truck, but I transferred a plate from my trade-in Jeep Compass which is considered a station wagon in Michigan. Therefore if you purchase a new plate it will be a truck plate, but I was able to transfer my car plate.
My Virginia plates are normal car plates, but my registration says body=pickup. Same for when I had my Ram 1500. I think in Virginia, maybe only heavy duty trucks have specific plates that state Truck on them.
I live in Pittsburgh. My dealer said lets run it thru as a car and see what happens. No need to pay for a truck plate, which PENNDOT will be glad to have you pay for. Got my registration back no problem.
