Read my posts. That is exactly what I did, I returned the car with no plates. I am sorry if I did not make it clearer. The personalized plates are yours, they do not belong to the car. You have two choices to make before you turn in the car. One, go stand in line at DMV and net new plates because you want to keep your personal plates. Two, take a screwdriver with you when you turn in your car and when you get there, remove your plates. You are making an issue where there is no issue. As I said before, the dealer deals with it all the time. They have a permit from DMV, as does the Auto Club, to change registration and request new plates.
