I have a different approach to repairs, spares and availability (though I am someone who extensively rebuilds an overland vehicle and does all his own mechanical work).

Firstly, I disagree that 2WD cars are easier to work on than 4WDs. I can lie under any of my cars and access all the undercarriage. I can remove the shock absorbers or rear axles, differential from my Landcruiser without even using a jack. Accessibility is far easier.

But getting on to the philosophy of repairs. In my opinion you should set off in a vehicle which is in excellent condition, something that makes no funny noises, has no leaks, no grinds between gear changes etc. All these things should be fixed before you leave.

I am not familiar with Africa but in general in developing countries, facing repairs is not like Europe. Mechanics are untrained labourers who fix problems. They don't call up a supplier and get you a new original part in a day or two. They will use their skills to keep an old part in service. So in general, part availability is not so relevant. More important is that you drive something which is well made. The idea is to avoid needing to visit these kinds of mechanics.

If you are able to do you own work, take service items such as filters and belts, and a decent tool set. If you have a major breakdown, you can make the choice between fixing an old part locally, or buying (most likely importing) the part you need.

In my opinion In general would avoid European cars - they are made for smooth roads and moderate temperature ranges. Cheaper makes (French cars, Fiats etc) are these days pretty flimsy; German cars are technically overcomplicated. I would go for a Toyota or a pre-2000 Nissan (before they became Renaults). An exception to this might be Dacias, they look like they are up to a bit of a beating. Or, go for a pre-1995ish car when things were generally better built and mechanically rather than electronically controlled.

Just my opinion. But I doubt you would regret buying a late 1990s diesel Toyota Corolla.
