The CITROEN C4 (2004-08) 5DR HATCHBACK 2.0 HDI DPF 138 VTR+ AUTO6 is a roomy five-door family hatchback, sitting in the popular used-car class between smaller runabouts and larger estates. It pairs a strong diesel engine with an automatic gearbox, offering an easy-going choice for everyday journeys and longer motorway trips. Mycarcheck.com has recorded 45 look-ups covering 25 different VINs, a useful snapshot of interest rather than a measure of all cars on the road. The checked examples average 99,000 miles and around 4,000 miles a year, with about 4.6 previous keepers; the average private-sale valuation is £1,100 in these checks. The C4 suits commuters and families seeking space, an automatic drive and diesel range, while its styling and comfort distinguish it from rivals such as the Ford Focus and Volkswagen Golf. Check condition and service history carefully before buying, as age matters more than mileage or a low asking price.
