The PEUGEOT 406 (1996-04) 4DR SALOON 2.2 HDI 136 SE AC SN is a four-door, diesel-powered family saloon, designed for comfortable journeys rather than city-car running. In the UK used-car market, it sits among older, roomy alternatives to estate cars and hatchbacks, offering a traditional boot and a formal feel. mycarcheck.com has recorded seven checks across five VINs, so its figures are a small snapshot, not a market average. Those checks show an average private-sale valuation of £400, 125,000 miles recorded, about 10,000 miles a year and nearly four previous keepers, context when judging an individual car’s condition and price. The 2.2 HDi’s strong, relaxed character and saloon comfort suit families, regular commuters and longer-distance drivers, while the SE trim and air conditioning add everyday appeal. Against Mondeo, Vectra and Passat rivals, the 406 is known for a notably composed ride and understated style; check service history carefully before purchase.
