An overarching theme I've seen that definitely relates to your situation has a lot to do with third world countries adding crypto acceptance to all kinds of situations. It's pretty tough when people don't really have access to a lot of technology in those countries because all of a sudden cryto's reach is definitely shortened. Auto dealers in a few first world countries do accept crypto and people who sell their cars independently definitely do accept whatever form of currency they want. Maybe it's just a time aspect.
