I don't know about other states but in California, having a front and back license plate is the law. It doesn't matter if you are a Corvette owner or other luxury car owner, if the police or highway patrol wanted to pull you over for no plate, he/she can...and you will be cited. I understand that many corvette owner and other luxury car owner have been driving for many years and have not gotten caught yet. I say to them, "Great for you" but remember that of all the thousands of vehicles on the road, sooner or later, they will find you.
Changes are that if they pull you over for not plate, they can almost find other stuff in your vehicle that is not legal as well (like guns, drugs, non-carb legal header, intake, etc.) Heck there was this one case, where a highway patrol pulled over a vehicle for broken rear brake light and founded his wife in the passenger of that vehicle. Oops, unlucky guy for cheating on a Highway patrolman's wife.
