The second-generation Citroën C4 (codename B7) marked a conservative turn compared to the audacity of the first iteration (abandoning the fixed-hub steering wheel and the coupé version). Based on the PF2 platform (shared with the Peugeot 308 I), it focused entirely on ride comfort, spaciousness, and a generous boot volume (408 liters). Facelifted in early 2015 (new 3D headlights, 7-inch touchscreen, integration of BlueHDi and PureTech engines), it had a discreet but solid career. In the used car market, diesel versions (HDi, e-HDi, BlueHDi) are ubiquitous and particularly sought after by high-mileage drivers, although they show major reliability disparities depending on the emissions control generations.
The Citroën C4 II is an excellent compact car for high-mileage drivers seeking comfort at a low price, provided you choose the right diesel engine. The 2.0 HDi 150 is the top choice for its robustness, followed by the modest but indestructible 1.6 HDi 92. The 1.6 e-HDi 115 is an acceptable compromise if the injectors have been replaced. However, BlueHDi versions should be heavily negotiated or avoided if the AdBlue tank is original, at the risk of a €1000 to €1500 bill. On the petrol side, steer clear of VTi, THP, and PureTech engines that haven't been meticulously maintained. Finally, opt for a manual gearbox or the true EAT6 automatic gearbox, avoiding the dreadful BMP6/ETG6 automated manual gearbox.
