The white on black is so popular that I've heard people inquire about it at the DMV and get upset when the person working there tells them it doesn't exist!
The Reviver "RPlate" is strange to me. I can't imagine paying that much myself. BUT, I can see a huge market if they're marketed toward lessors. I have to imagine I'm not the first to think of this, and maybe this is already out in the wild...but if someone missed payments and the car was to be repo'd, it'd be hilarious if the Reviver plate changed to "REPO ME" or something.
