The PEUGEOT 406 (1996-04) 4DR SALOON 2.0 HDI 110 GTX AC SN is a spacious, conventional four-door family saloon from Peugeot’s mid-sized range. In the UK it sat among practical alternatives to the Ford Mondeo and Vauxhall Vectra, offering a comfortable, air-conditioned choice rather than a small city car or an SUV. Its diesel engine suits longer journeys and regular commuting particularly well. With four mycarcheck.com look-ups covering three different VINs, the available sample is small, so its figures are an indication rather than a full picture of the model. Those checks show an average private-sale valuation of £300 and average recorded mileage of 243,000 miles. The cars averaged 13,000 miles a year and three previous keepers, suggesting examples may have seen substantial everyday use. The roomy cabin and air conditioning suit budget-minded commuters and families wanting space for comfortable longer journeys, while its diesel character favours regular motorway use.
