Carnet or ? Ghana to Namibia
 

Okay, maybe a long shot but then if the info is not on the HUBB then I don't know where!
Anyone have any idea how one would go about temporarily importing a vehicle (registered in Ghana) into SADAC countries (SA, Namib, Botswana etc)? From SADAC the vehicle would be going elsewhere and more than likely not back to Ghana - so a carnet originating in Ghana would be out of the question. I would probably ship the vehicle into Walvis bay, so bluffing my way past some deserted outpost would be out of the question. I was thinking that a deposit with a bank or ? But then would that have to be for each country or?

Advice on this would be really appreciated, spent a good few hours trawling the search functions but no real joy, in fact I am still confused as to whether a Carnet is even required or not. First hand experience would be valuable.
thanks in advance,
Gil
