In my state, the license plates are made by inmates at state prison. You can't get one unless you pay tax, title, and license fees on a vehicle at the county tag office, before which you will have presented said vehicle to an official inspection station for inspection. Whole thing can cost at least $800 (price depends partially on what they figure it's worth, so I'm thinking that's what I'll have to pay to title my new Swing).
So here in NC, not possible, I'm thinking.
