Budapest-Bamako
 

In was wondering how to sell a car in Bamako. Do the participants of Budapest-Bamako for example each sell their car individually or do they have one middleman that buys all or have an organised auction, like in Banjul.

Put an "A Vendre" sign on it and just wait. :)
Or you could approach the car dealers in Quartier Fleuve, like Yussuf beside the Bistro Bafing (lovely place btw).
Car market in Bamako appeared a bit saturated in January, and dealers were pessimistic. The city is getting congested so perhaps a good thing if it slows down.
Theres always a buyer if you have the right vehicle.
But dealing with the "business-men" can easily become exhausting.

OR, you can always rent the thing to me and I would be happy to get it back to Europe for you :)
