Build this. Give it a diesel engine and towing capability. I will buy it.
Both Hyundai and Kia make small, flatbed pickup trucks in Korea that I drove when I was stationed there. Great little trucks. Diesel engines, good gas mileage, could haul anything that would fit in the bed. I wanted one of those when I came back, but they weren't selling them here in the US.
This would fill a niche right nicely.
