I live in Puebla about 6 months a year. I have cars in both the U.S and Mexico, which is fairly expensive. I am thinking about selling my US car (which is older) and just having my relatively newer Mexican car, which I would drive back and forth. My question is, is there a limit to how long my Mexican car can be in the US? For instance, would 6 months be allowed?

Any insight on this would be helpful.
