So, Zona Franca is such a big DUTY FREE - a free trade zone.
There are two Zona Franca in Chile: in the north of the country in the city of Iquique and in the south in Punta Arenas.
It's really possible to sell a car here, even from Russia, and you won't have to pay any customs duties or taxes (*there are certain restrictions). In the rest of Chile, and in many other South American countries, it will not be possible to clear a used car with foreign license plates - the law prohibits it.
After crossing the Darien Gap to South America, we bought a jeep in Bogota (
