Vehicles & Customs

Yes, we have done it recently. Annually for the last 35 years, through all the changes.
Until this year, because we are applying for our Permanent Residency, we have purchased the TIP on line. That way we don't have to wait in line at the border, or even stop. We also make a run to Tijuana, walk across and get our FMM. Specify 180 days. There is no connection to the vehicle at all. The FMM automatically expires when the time is up, and that's it. At this time, and who knows for how much longer, FMM's are hand written, usually by the person who wants it. It's possible, but don't see how the number and the vehicle would be connected. I thought the vehicle deposit HAD to be paid by credit card.

Sorry for being unclear. When I asked if you had "done it recently", I specifically meant have you entered with your vehicle on a 180 day tourist card, then flown out of, and back into Mexico during that period, then driven your vehicle out within the original 180 day period. I was wondering if, in that situation, there was any particular advantage to having purchased the TIP on-line, instead of at the border on entry.
Someone has noted that when you enter Mexico, the tourist card has a little block where you indicate arriving by land, sea or air. Check "land"....because you arrived with your vehicle....and you may be caught when handing-in your tourist card at the airport: "Where's your coche, Senor?"
The deposit can be paid in US cash or by credit card. We've always paid cash and have never had a problem getting it reimbursed at the border on exit. Obviously, we have to line up at the Aduana counter to get our money.....the only disadvantage.

Regardless of what the law says, one would think there would, or should, be provision within it for an emergency situation where one has to return home on very short notice.....as long as the vehicle eventually leaves Mexico within the original 180 day TIP period. But that would make too much sense, I guess.
