The oldest of Citroen'Â’s three small cars, the C3 was responsible for kick-starting the firm'Â’s design renaissance. The good news is you really rate the low running costs. The curvy five-door scores well for fuel consumption and servicing costs. But it'Â’s far from the perfect supermini –– the handling is below par, while practicality could be better. However, the lowest mark came in the build quality category (85th). Citroen needs to improve the way the C3 is built before it can hope to compete with the best in class.
