Relocating bringing vehicle personal items taxes (Addis Ababa)

Hello everyone, If anyone can help I would be greatly appreciated. In August my wife and I will be moving to Ethiopia to teach at one of the international schools. The question that I have is there any one with expierence bringing their car and personal items to ethiopia.

I need to know if we brought our vehicle with us would we have to pay all the taxes and customs fees? I have owned the vehicle for 5 years, and we plan on taking it with us to our next job. Would we be exempt. or do we have to pay. can any one tell me roughly how much the taxes would be?

Please let me know how this is done

Thank you all for your help
