In my youth, Citroën made such unique cars. Quintessentially French in design, nothing else on the road looked like them or drove like them. The Deux Chevaux was truly unique. I first rode in one in my school days. The local taxi driver, who was paid by the school district to drive us the three miles to the nearest school bus stop in the morning and take us back at the end of the school day, had one for a while. I recall in the winter the driver would hang a paraffin heater off the gear-shift. He probably wouldn't get away with that now.
Despite the name, the original 1948 version came with a 9hp motor and the final versions in the 1980s had 29hp motors so I'm not sure I understand the two horses name but it has something to do with tax rates based on cylinder dimensions rather than motor output.
I spotted this example on the Pont Dieu over the Canal Saint Martin in the 10th Arrondissement of paris.
