The first-generation Citroën C1 (factory code PM for the 3-door, PN for the 5-door) is the result of the "B-Zero" industrial project jointly led by the PSA group (Peugeot-Citroën) and Toyota. Produced in the TPCA factory in Kolín, Czech Republic, it shares 90% of its parts with the Peugeot 107 and Toyota Aygo. Designed as an ultra-compact (3.43 m) and economical city car, it stands out for its agility and negligible running costs. The model underwent two facelifts (Phase 2 in late 2008, Phase 3 in early 2012) which mainly modernized the front end and improved sound insulation. Overall, it is an extremely reliable vehicle, supported by the excellent reputation of the Toyota-sourced 3-cylinder gasoline engine.
The first-generation Citroën C1 is a benchmark choice for a budget used car purchase. Its 1.0i gasoline engine, designed by Toyota, is a model of robustness if basic maintenance is respected. It is absolutely essential to prioritize gasoline models with a manual gearbox, ideally post-2009 (Phase 2) to benefit from the reinforced clutch and more reliable water pump. Avoid the automated manual gearbox (Sensodrive) which degrades driving pleasure and reliability, as well as the 1.4 HDi diesel engine, whose presence under the hood of a micro-city car is an economic and mechanical nonsense. Before purchase, a meticulous inspection of the trunk for water ingress is imperative.
