The CITROEN C6 (2005-12) 4DR SALOON 2.2 HDI DPF 173 AUTO6 is a large diesel executive saloon, offering distinctive styling and comfort rather than hatchback practicality. In the UK, it was a rare, upmarket alternative to the BMW 5 Series and Mercedes E-Class. It suits professionals, couples and families seeking a spacious, quiet car for longer journeys, but its size and potential upkeep are less suited to new drivers or tight-budget city use. The 2.2 HDi engine and six-speed automatic favour relaxed cruising; its famously smooth ride and bold design give the C6 unusual character beside more conventional rivals. mycarcheck.com has recorded two look-ups for this version, covering one VIN, so the figures are a small snapshot. The average private-sale valuation was £4,100, with 104,000 miles and two previous keepers; annual mileage is shown as zero.
