Hi Veronica, you can’t actually drive as far as Ecuador as you can’t get through the Darien Gap from Panama to Colombia. I do know some people who have done this, though, but they have to put the vehicle on a ship in Panama and send it across the sea to a port in Colombia or Ecuador. Even if you do this and even if you have a resident visa, as a foreigner you can’t import a vehicle into Ecuador. So in my mind, that means you could only have it here as long as your tourist visa is valid.
You might want to talk to a customs specialist about this to learn more. I’d suggest you reach out to Sandra Baquero: SanestarInternational@gmail.com
