Thanks fig, yeah thats pretty much the answer I was fearing (and expecting!) Still, at least there are more of them about than RHD Ghia cab's!
Can you tell me, what are the structural differences between a samba and a normal split microbus? Obviously, the samba has the sunroof and the little windows on the roof, but is there any stucture added to the bus that isnt on the microbus? Like with the Ghia cab, for example, there is a whole support structure in the back to make up for not having a roof, and the body structure from the doors back is very different to the hard-top. Is there anything similar on the samba? I know about the pop-out windows and the sunroof mechanism, but could one (conceivably - just theorising here

) get a split microbus and cut the holes in the roof and add all the samba bits? As far as I have been able to establish, the samba is just a microbus with "deluxe trim". So didnt the factory just take a microbus shell and make it a samba when they were built, or is there more to it than that?
