In the UK it sat between mainstream family cars and more expensive executive models, offering a comfortable alternative to an estate or hatchback rather than a small city car. mycarcheck.com has recorded 17 checks covering 10 distinct VINs, a modest sample that offers a useful snapshot rather than a market-wide verdict. Those checks show an average private-sale valuation of £400 and average recorded mileage of 128,000 miles; annual mileage averages 9,000, with about four previous keepers. This HDi diesel saloon suits families, commuters and long-distance drivers wanting space, a calm ride and air-conditioned Executive comfort. Its efficient-for-its-era diesel character and understated styling helped it compete with Ford Mondeo and Vauxhall Vectra, while the 406 is valued for comfortable travelling. At this age, condition and history matter most.
