I see no reason why it can't be true. He left equiped for a long distance desert trip (raid). He had water and food for more than two weeks. At no point was his life in danger. His car broke down several dozen kilometers from a town, and he knew that. He chose not to go back on foot, because he didn't find that fun, and he wanted to have fun. He's a mechanic and tinkerer, went there on holiday, the military turned him around, so he found something else to do: build a motorbike. In a subsequent trip he turned the same car model (Citroen 2CV) into a floating barge, just to cross a river. He could have crossed that river farther away in a multitude of ways, but this is his idea of fun. tl;dr: guy can walk back to civilization in a day or two after his car breaks down in Morocco, he chooses to build a motorcycle from car parts instead. Why? For fun. Edit: I feel that reading the full story on the original site (in French) dispels much of the doubt.
