Can anyone explain California's reasoning for this restriction? Do other states have similar prohibitions? I would think that if an older car that originally had the period correct plates and an enthusiast desired to backdate and informed the DMV, what is the big deal? Its not as if the DMV has the color or model of the plate in their database, its alpha numeric after all. Also why the 69 vs. 71 cutoff between individual and commercial vehicles? What is the California cutoff date for antique vehicle registration and plates?
