I would guess a lot....can they even ask for ID or citizenship status?
I doubt they can ask...
This is just my observation but from time to time when people come through here loaded to the brim with household stuff- going TO Mexico, they always seem to have really nice new pickup and often wife is following in new car. I have talked to some of these people, they are moving back to Mexico and I have wondered once they cross the border is it even possible to repo vehicles from there if they don’t make payments?
Just my curiosity.
