Porsche 356's have cabin ventilation, although as with the later 911 it's not very good.
The Volkhart V2 Sagitta (1947) has inlets at the front, could be for the cabin ventilation, front brake cooling, horn, or a front mounted oil cooler, I do not know for sure but if I were to guess it would be cabin ventilation (actually looks like a fan). Cracking a window open I suppose would be an option.

Ventilation system has to have inlet and exhaust ports. I don't see any ports for cabin ventilation. We know how bad ventilation early Beetles had. Why this car would be different in any way? In one of those pictures driver's side window is open. That gives us a hint how well the ventilation system works.
24 hp engine doesn't need much cooling. Beetle had a fan sucking air through that grille under rear window. I would't compare that to a 90 kW CLA. Volkhart V2 is sealed like a bottle compared to a modern car.
