Sanantonio: You may, indeed, drive your Mexican plated car in the USA when you wish to visit. We do so and it is perfectly legal. Just be sure to have your Mexican FM3 visa with you to establish the fact that you live in Mexico. Even better, have a Mexican license to present, as they aren't likely to try to take it from you if you have been really bad. If the car is not registered to you, I would suggest that you have the owner provide notarized permission, your name on the insurance in Mexico and the temporary USA policy for the trip.
