The CITROEN C6 (2005-12) is a large, distinctive executive saloon, rather than a family hatchback or SUV. It was Citroën’s flagship, aimed at buyers wanting comfort and refinement, and competed with familiar premium choices such as the BMW 5 Series, Mercedes-Benz E-Class and Audi A6. Its unusual shape and limited numbers make it a rare sight on UK roads. mycarcheck.com has recorded 549 look-ups covering 223 different VINs, giving a useful snapshot of this uncommon model. Checks show an average private-sale valuation of £3,500 and average recorded mileage of 106,000 miles. Typical annual mileage is relatively low at 3,000 miles, while cars have had around four previous keepers on average. These figures describe checked cars, not a guarantee for any individual vehicle. It suits comfort-focused commuters and families seeking space, individuality and relaxed travel, with distinctive styling and a cushioned ride setting it apart. Buyers should check condition and running costs carefully.
