Mexican residents can bring a non us legal car to the us for up to a year. If you’re a US citizen living in Mexico it is more complicated but I think you should still be able to bring it for a year.
It's an interesting arbitrage question. When I do a search to see what they cost, they aren't that cheap: approximately $20k USD for a starter (Dolphin Mini). And, then about $50k USD for a minivan (M9). I was wondering if there was a weird lease model which could work for independent Mexican residents or expats, but I don't think there is.
