Can't fly out while you have a vehicle in Mexico?? True?

Well, we seem to have a couple of threads going on here but to answer tallyho69, you apply on line, pay online, print off your Tourist permit and receipt. When you get to the border you present the TP and receipt, have it stamped and you're on your way. If you do your TIPs on line too as I've done for the last 5 years, the wait time at Nogales is greatly reduced.
