I do know that old plates from year of vehicle are a little problem, as nobody wants to "surrender" a unique special numbered plate, and are forced to keep insurance on vehicle until plate "expires". There might be a way around this, but its up to local tag agency.
I in the last decade have only dealt with my local county tag agency, they are fast, no lines, and easy to deal with, so who other to recommend is not something I can suggest.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
