The Namibian car market appears to be very similar to the South African one. The Toyota Hilux should lead the sales by far, ahead of the VW Polo Vivo (the sedan is clearly preferred here), Opel Corsa KB and Toyota Yaris. The Isuzu KB, Nissan Hardbody and Toyota Corolla are also successful.
This speculation is based on the observation of the streets of the capital Windhoek through recent YouTube videos. Please get in touch if you have more info about the Namibian car market.
