Talley Ho: Where did you get that info? her is a cut and paste from Mexperience
entering Mexico with a Residente Temporal permit:
Holders of Residente Temporal (with or without work privileges) and Residente Temporal Estudiante may import their car to Mexico using a Temporary Import Permit (TIP). The vehicle will remain legal in Mexico for so long as the resident permit remains current. For details about residency permits, see our Mexico Immigration page.
