The CITROEN C6 (2005-12) 4DR SALOON 2.2 HDI DPF 173 LIGNAGE is a large, distinctive executive saloon, aimed at buyers wanting comfort and individuality rather than a conventional family hatchback. In the UK it sits among premium company-car alternatives, though its unusual styling makes it a rarer sight than German rivals. Mycarcheck.com has recorded 29 look-ups covering 12 different VINs, so these figures offer a modest snapshot. The average private-sale valuation is £3,300, with average recorded mileage of 98,000 and annual use around 3,000 miles. Checks also show an average of about three previous keepers, useful context when assessing any example. The diesel-powered C6 suits long-distance commuters and executives who value a relaxed, spacious ride; it can serve as family transport. Its flowing shape and comfort-focused character set it apart from conservative BMW and Mercedes saloons. As with any older, uncommon model, review its history and condition carefully before buying.
