I've driven off-road and it felt like driving on pavement. Smooth and strong. I'm glad I found it and amazed at it's ability to do anything on and off the road.
4WD, hard and soft tops, 30" tires, lights, overall build (solid as can be)
perhaps a longer wheelbase to add more storage/trunk room, maybe incorporate some of the Jeepster qualities (more aerodynamic qualities, sloped windshield) or just put the Jeepster into production, it would be a huge seller, including the Willy's concept as well.
