Algeria-Niger-Chad-Sudan

[sebch]

Hi all,
My latest project is due to take place from mid-february to oct/nov 2003. The (not so revolutionary) idea is to drive from Switzerland to South Africa with a friend. The only thing that might be a bit thrilling is that I want to drive a Citroen 2CV, like in the good ol'times. Route would go through Algeria, NIger, Chad, Sudan, Ethiopia, Kenya & straight down the coast from there.

I have 3 questions about this route:

1- I've read on several websites & in books (incl Sahara overland) that the Arlit/Agadez area is now unsafe. Does it mean you have 90% chances of being robbed if you travel there coming from Tam? I'm NOT planning to get on an organised tour & just want to cross the area (transit): no visit to the Air is planned on our own. Is this transaharan option now therefore impopular or do I get a chance to find overlanders to travel with from Tam on? I don't want to drive from Tam to Agadez with one car alone.

2- Aparently safety & politics will allow the Lake Tchad route (Nguigmi-N'Djamena) to be used. But, same question, is there a lot of trafic (When I say "a lot" it's " more than one landy in a month"). And can you find petrol on the way (2cv's were never diesel...)?

3- In which countries you need to get a carnet de passage?

Thanks in advance
