Drove to China from Portugal with a old car. Tried to find the concentration camps in Xinjiang. Got detained twice, was so much fun! Chinese police a really really funny (if you have the right passport).
It took 11 month an 40k km all in all. But it was 80% detours. Had to leave my car at the boarder to China. No chance to take it there. The most magnificent place on the way was Iran for sure. Lovely people with a hate for their own government and not afraid at all to voice their contempt for religious fanatics, the city dwellers at least.
