This one was at the Stouffville (north of Toronto) car show today. By the front door handles (suicide doors) I'm guessing a pre-1965 model. The car was wide open and we got a peek under the hood- and through the roof.
The boxer engine of 425cc is right up by the bumper, we were confused with the two spark plugs but four intake runners till we figured out that the pipes on the right were exhaust, also acting as a heat riser for the carburetor. There's enough room for another trunk above and behind the engine!
A photo through the removable fabric roof shows the utterly simple cockpit. Basic utility transportation at its finest.
