Well Vauxhall was a lucky guess but I have to say I really don't know any more about this strange-looking car.
If I just give you my observations on what I can see and a guess on dates - that might lead to the solution.
My immediate thought is that the car is based on a pre-WW II Vauxhall (or could it be a Bedford van/light commercial?).
I say that because the driving position seems quite high.
Secondly I would say the wheel diameters are smaller than what one would expect on a pre-war car.
Perhaps the car was built during or just after WW II as the bodywork seems fashioned from any metal available at the time.
My other thought is that I find it strange how the bonnet (hood) opens in that fashion and there appears to be a lot of wires visible but no sign of the top of the engine.
I would guess the car is powered by some type of alternative engine/fuel owing to the constraints of the day.
Those are merely observations and I could be way off beam.
Please open it up again if I'm wrong.
