A Citroen 2CV is pretty much tinfoil with an engine attached. It's definitely feasible even with hand tools.
With respect to survival, if you head into a desert, you take supplies galore. The 12 days was probably due to the heat so you can only work at dusk/dawn and seek shelter during the day to conserve water/rations. 2CV is very simple and can carry a lot of stuff. It's nearly ideal.
I take a 72 hour pack and am happy doing 50mi+ on foot if i go more than 10mi from home after a couple of experiences being stranded in rural areas in the UK. Imagine what that guy was carrying in the desert!
