I've been dreaming of building something like this for a decade! Not as extreme off-road like this, and more focused on high speed and stability on-road and light off-road but still good travel on the suspension.
Exactly, its pretty uninspiring as is. Looks goofy, slow with really terrible wheels/tires. Needs to be fast with inspiring performance and cosmetic improvements would also help a lot. I see nothing here that a quad can't do far better.
