99.9% of 4WD vehicles never go off road. (I made this number up, but you get my drift)
99.9% of vehicle owners want all the creature comforts : aircon, plush seats, high end sound.. blah blah blah.
What you’re suggesting is a a hard core, super capable off road vehicle whose main use would be racing competitions or Sunday arvo cruises to a pub for lunch in fine weather.
In short, your target market will be a tiny niche of cashed up enthusiasts. It would surprise me if you could sell 50 over a 10 year period.
Despite my negativity, I think they would be a barrel of fun to drive, I’d love one.
