Hi Cees,
I believe a lot of cars "left" African countries after colonies gained their independence ....it was a way of getting some value out for those who were leaving and the currency had quickly devalued.
I can speak for Mozambique were as a kid in the early 70s I knew the owners of a pagoda , a blue 190Sl and .... a silver 300 SL R . All taken to Europe after 1974 .
I remember 170 convertible with 36k miles and a adenauer 300 ( think it was a 300) in a scrapyard ! .... Of course plenty of sedans like the fin tail and 60s early 70s models w108/9/11/12 .
I would safely bet there isn't one pagoda there today. But there was a w112 convertible I saw in 2000s but I believe was a recent import from South Africa.
Regards
Pedro
