Hi again,
first problem was, that you need TIME, because there told us to come tomorrow and then tomorrow and then in 3 days... and we had to be very patient... So - one week later than expected - we spent all day in the small harbour (exactly 26 hours were gone between our arrival and the departure of the ferry). All was arranged, we asked every hour if all is going to be ok, no problem. In the middle of the night, after we had all our exit stamps (immigration for us and customs for the car), the manager that we didn't see all the time decided that they can't/don't want us to ship (we were the only car and I had the impression that it was not an usual thing for them to put a car on the ferry, that's why I don't even know if they would do it again)!!! So we had again to discuss and discuss and discuss...
Second problem: the price - there are no official prices so you have again to be very patient in your negociations (we paid as far as I remember about 300 EUR for the car (ferry, crane, loading & unloading on departure) and the tickets for us (official price), I don't remember the price).
Third problem: you can't drive on the ferry, so you need a crane (firsey said that we could arrange that we can drive on, then we had to call a crane in the middle of the night...). The crane was an old Mercedes truck, which was first unable to carry our car, although we told 300 times the weight of our car... The car was balancing in the air, fixed at one point with chains and straps that didn't seem to be very strong, the truck began to tilt and we had some pains in our stomachs, so they had to load a lot of scrap on it. After this, we had some damages on it (the roof was a bit buckled, the paint gone at several spots

)
One positive thing: We could drive off in Douala, because there was flood.
So it was a nerve-racking story - one one side always great to remember and one day to tell our grandchildren, on the other side, a thing for sure is: never again!
So if you want to experience real Africa, do it!!!
:D
Wish you a nice trip,
Christelle
PS: Fourth problem: we had our dog with us and several people looked at it like in the Asterix comic (as they would see a appetizing roast)

and wanted to buy it :?
