The CITROEN C6 (2005-12) 4DR SALOON 3.0 HDI V6 DPF 240 EU5 EXCLUSIVE AUTO6 is a large, premium four-door diesel saloon, aimed at buyers seeking comfort and individuality rather than a mainstream family hatchback. In the UK it sits among executive cars, offering a distinctive French alternative to familiar German saloons. mycarcheck.com has recorded seven look-ups across six VINs, so the sample is small; within it, average private-sale value is £5,200, average recorded mileage 73,000 miles, annual mileage 4,000 and previous keepers about 2.1. These figures suggest a low-mileage example in the checks, but condition and history matter especially on an older, uncommon luxury car. The V6 diesel and automatic gearbox make it well suited to relaxed motorway journeys and travel for couples or families, while its striking, unconventional styling and comfort-focused ride set it apart from rivals. Choose it for character and refinement, not the simplest, cheapest-to-run used executive saloon.
