I work at an exotic car rental branch. I have plenty of customers that rent our cars and ask us to take the ID tags off the key ring (understandable). Then I have some that INSIST they get the same license plate each time and will flip out if I give them the same model as usual but with the plate one digit off.
They’re trying to make the appearance to whoever that they own the car and get themselves in a trap where they have to keep renting to keep up the illusion. That charade never lasts long.
