The concept is quite interesting even if some see it as ugly. It has a chassis that is doubled floored to hold all the running gear and engine. This allows a variety of bodies for different uses to be bolted on. The idea was taken from coach/bus construction.
This concept took it a little further with the use of the final vehicle being taken into account and could be reconfigured into an ambulance, fire truck or even a van.
The car only has two doors, but five seats.
