yet another aduana question concerning vehicle permit

[Doyle Phillips]

My vehicle registration has expired while in Mexico (on my tourist permit).

I have to go to Texas just for a day and Mexican aduana requires that the car permit be closed out any time i leave Mexico and for that matter my tourist card must also be turned in on exit.

I have read on line that aduana requires EITHER a valid registration certificate from my home state OR a vehicle title. I have the title.

Have you or any one you might know come in on the Mexican 180 day tourist permit and used only the vehicle title in order to get the aduana permit?

When i came into Mexico in December i had both registration and title so i did not notice whether aduana required both. Thanks, Doyle Phillips
