This, the littlest in the Citroen range and sister model to the Toyota Aygo and Peugeot 107, rounds off Citroen's trio (four if you count the C3 Pluriel) of town cars.
Taillights are one of the defining features of the C1, one of three sibling models from Toyota and PSA-Peugeot Citroen. Headlamps are also unique.
