If you were worried that Citroen had somewhat lost its Mojo in the 1990s and early 2000s, then the C6 was a reminder that this company can think outside the box and produce cars that combine quirkiness with practicality.
The used Citroen C6 may have first launched in 2006, but it draws inspiration from a range originally designed in 1928. Back then the C6 was the height of automotive luxury and shipped tens of thousands of examples at a time when this was rare, with endorsements from public figures helping to spread the word.
The modern day second hand Citroen C6 got off to a bit of a slow start, in part because of the high asking price. But on the used market it has become a bit of a gem because of its reliable mechanical elements and entirely unusual aesthetic ethos.
Bang for your buck
When looking to buy a used Citroen C6 you've got to factor in the invariably steep depreciation, which has been enough to put off many buyers.
However, you can balance this out against the idea that if you wanted an equivalently specified model from a German manufacturer, you would be paying upwards of £10,000 more in the first place, which should put things in perspective.
Even the base model approved Citroen C6 comes with that delightfully smooth Hydractive suspension, along with air conditioning that is divided into two zones, nine airbags, Xenon lights and a comprehensive onboard computer that monitors virtually every aspect of the car, including the pressure of the tyres.
That being said, you're more likely to find the Lignage and Executive model options on the used market since most new buyers wanted a little more out of the C6 from the get go.
What you'll pay
Although the Citroen C6 is relatively rare in the UK, it's not impossible to find used and if you are the second or third owner then you'll know that those who came before you have taken the biggest hits in terms of depreciation.
Top end models sold for almost £40,000 in 2006, with two thirds of the original cost being shed over the first 36,000 miles or three years on the road.
What to check
This is a technically advanced range so you don't want to tempt fate in terms of the condition of its electronics. Ensure that there is a full service history in place for any used models and pay close attention to the suspension, because this is a complicated and expensive bit of kit.
Used Citroen C6 parts are not too expensive as they are shared with some of Citroen's other models. Brake pads are £45, with a radiator setting you back £245 and a replacement clutch topping out at £205.
How it drives
The V6 engines, available in either petrol or diesel variants, are both decently powerful without being completely over the top, although there is a smaller 2.2 litre HDi option available.
The Hydractive suspension is particularly impressive as it manages to keep the car completely level in corners and will iron out even the bumpiest tracks, all without needing driver input.
