Vehicles & Customs

We drive down every year, and have for 30+ years.
Get your vehicle permit on line. No extra cost, easier. Then, when you get to the border, you get your FMM (visa) When you fly home, you will surrender your FMM at the airport, and get a new one on the way back, included in the price of your ticket. Return your vehicle permit before 180 days at the border. They come out, remove the sticker, and you will be credited for your deposit in a day or maybe two. You do NOT need to turn in your FMM. As aduana says, "It expires."
Very straightforward, very easy.
