@chronogn is right. You will also need a Temporary Vehicle Import Permit (TIP) to drive outside of certain areas of Mexico. We've been pulled over three times already and they asked for the TIP paperwork each time. Gotta have it! They have also asked to see the vehicle's registration and our US drivers licenses as well.
As of right now, we're thinking 3-6 months. Perhaps longer if we really like it! :)
