Selling a car in Ethiopia
You would only be able to sell it to a person with duty free privilege (diplomat or aid worker) and the procedure is cumbersome. Can be done but takes time.
If you find someone with an import permit, you could sell it duty paid, but the duty on 4X4s is 160% of the new price with only a slight discount for older vehicles. Since the duty is so high, you will have to sell your vehicle at a real low price to make is sellable. You would be better off shipping it back. Also, you would need to sell to someone that could pay be check or transfer from a third country as you cannot transfer or take more than $1,000 out of the country.
