Citroën C4 Cactus
The C4 Cactus was Citroen's family hatch with a difference, launched in Britain in 2014 with bolt-on Airbump panels, a featherweight body and a cabin that swapped conventional dashboard hardware for a central touchscreen. UK buyers mostly chose the 1.2 PureTech petrol, while the 1.6 e-HDi and later BlueHDi diesels appealed to high-mileage drivers. The 2018 facelift softened the styling, added Progressive Hydraulic Cushion suspension and repositioned the car as a value-focused C4 hatchback rather than a small SUV. Reliability is simple and cheap, but the PureTech wet belt is the defining risk: a neglected belt can shed material into the oil pickup and wreck the engine, so proof of correct oil and on-time replacement matters more than mileage. Rear space is modest and the pop-out rear windows divide opinion, yet low running costs, a comfortable ride and strong parts availability make a well-maintained Cactus a sensible urban runabout. Avoid tired ex-city cars with patchy histories.
