I have lived in MX for four years, and I have an FM3 and may get an FM2. My US driver's license expired. Since I have no plans to live in the U.S. (just visit a couple of times a year), I obtained a MX driver's license (yes, I actually took it and passed; no coyotes for me!). I want to buy a new car, but apparently buying a MX car is not recommended. My questions are: (1) Can I buy a car in the U.S. (cash) and bring it back to MX using my MX driver's license but no American license or (2) if I buy in MX (cash), can I enter the US with appropriate documents and just a MX driver's license or, as a U.S. citizen, do I HAVE TO have a American license (I don't have a home in the U.S.; I visit my sons who live in two different states). Thanks for any advice! Maya
