I don't think they got an ID # other than whatever VIN the car they used had. A VIN assigned by a state just means that the car they started with had no VIN. Rust damage, crash damage, Dynacorn body etc. There is an Eleanor licensing group that also issues a tag but not a production number. Google eleanor tag and you'll find several variations. None specific to Unique. Is the state issued VIN from where Unique was shutdown? I remember there were several cars seized without VINs.
