This is strange. I have never seen a microcar before and seeing one at youtube is amazing. It still runs after all this year. The microcar is more interesting to ride as compare to motor bike.
What is a "MICROCAR"?
It is basically small car mostly with two seater built in the late 1940's- pre-1964 range with Engine sizes of 700cc or less (many are 250cc and 50cc) and 2 doors or less. Would you use this vehicle if it saves you petrol? I doubt it.
You can find great pictures of the wonderful microcar at http://www.microcarmuseum.com/ or http://www.youtube.com/watch?v=07ub5rBdrE4.
