I’ve seen one with ports on trails in Colorado.If they market it as niche item for the well-heeled socialite soccer mom or celebrities, I can't see it having wide spread success.
If its cheap enough to be bought by more average Joe types, and really gets put through its paces in the mud and rocks without too many failures it might go somewhere.
Mercedes Benz G-Wagen was touted as a competitor for Landcruisers in Australia. They had some pitiful failures on early extended media test drives in the outback.
No idea on price point, but don't see G-Wagen anywhere outside of Toorak or Bellevue Hills.
