And then there is the question of vehicle insurance. Your north of the border insurance likely won't cover you in Mexico, maybe for comprehensive but never for liability. Theoretically, you don't need insurance. But if you do have an accident you will want coverage unless unusually well heeled with lots of time on your hands to round up the cash. Rules in Mexico can be a little different, for instance, if someone rides a bicycle into the side of your vehicle the chances of you pleading your case, that they hit you, are slim. Insurance can help you with paperwork in a different language (the adjuster). That insurance must be from a Mexican company, but can be purchased through a Broker north of the border, even through the internet.
