Hi Jas, I have bought VW's over from SA in the past and been disappointed with the overall condition , but this is a very rare car and could be a great find if it is a genuine RHD Zwitter.
You will need to see photos of the chassis and body numbers to be able to check them and be confident that this is the real deal . From looking at the photos you can see the correct dash with start button , handle less ash tray but dose it have the two arrow Zwitter only speedo ? The doors look like correct ribbed ones but not sure about the interior , the steering wheel is 1956 > and the rear view mirror and visors are 1958 > . There was a RHD Zwitter advertised on this site a few weeks back for £13k and it sold but it was in much nicer original condition so gives you an idea of what to spend before shipping that could be around £2500 . Good luck with the purchase hope it happens , if you need any one to view it for you my brother lives in Cape Town and would be happy to help.
