My buddy, Ian, ran the Mongol Rally in 2016. He and his crew used a 1971 Morris Minor as their vehicle of choice. You essentially have to do it in a vehicle with under 1.0-liters of displacement. Here's a link to the post and video about it. Great little seven-minute short film.

Which would you choose? Personally, I'm thinking early 1990s Mitsubishi Minicab. I suppose a Mirage with the 1.0 would qualify, too!
