The issue with the plates (someone correct me if I'm mistaken) is that the plate is in your name and there could be liability or other legal issues. If I buy a car from you and you leave the IL plates on, suppose I then become involved in a hit and run or something worse. If someone saw the incident and reported the plate to the police, the plate would then trace back to you. How easy would it be for you in this case to talk yourself out of the mess, I don't know. Personally, I would rather not run that risk. Yes, it would be simpler if the plates stayed on but I don't mind waiting at the DMV to do it right so that both parties can then sleep with no worries.
Notarized Bill of Sale. /talk of legal fears with your name on old plates
It's highly unlikely that someone will purchase a car turn around and go out and risk racking up parking tickets and red light camera violations. But the only way you could really have that happen was if there was no record of the sale and date (which is why you need to get it notarized) of the car changing hands, legally. The only way that could really happen is if you threw a stranger the keys to your car and said "have fun". Under normal circumstances people complete legal documents that transfer the ownership of the vehicle.
Its for this reason that most states have a leniency period allowing the owner of a newly purchased (used) car to have a few days to register their new car before they face legal consequences. But it's the responsibility of the *seller* of any vehicle to know what to do with the license plates on their car because every state is different on this topic.
After the bill of sale is completed and notarized, the car has legally changed hands and the original owner is no longer responsible for the car, regardless of what the license plates say.
