Thanks and Update
Thanks for everyone's input. I can't believe how diligent the posters to this chat site are.
I got pinched for time and was able to justify (barely and it really is only a rationalization) purchasing a new Hilux. I'll need it eventually for some commercial endeavors and the price was rather reasonable by European standards. If worst comes to worst, I think I'll be able to resell it reasonably.
I'm making a very preliminary expedition to Mali next week. I expect this to be largely road driving, but perhaps a few desert pistes as well. I'm planning on packing the following:
1. Fuel jerry can (20L?)
2. Metric tools
3. Filters and belts
5. 1 extra tire/wheel
I think this is a fairly tame expedition, but I was wondering if anybody had any other necessities they could think of.
By the way, the price of the truck including tax here in Senegal was comparable to the prices quoted in France and Belgium. The insurance is very reasonable by U.S. standards and the cost of the carte brune was negligible. I don't think Mali will require any "extra" costs for the vehicle.
All in all, I'm very happy with my decision to buy, register and insure locally.
