The PEUGEOT 406 (1996-04) 4DR SALOON 2.0 HDI 110 LX AC SN is a roomy, four-door family saloon from Peugeot’s traditional mid-size class, rather than a hatchback or SUV. It offered comfortable long-distance travel and a practical boot, making it a familiar choice for UK families, business users and drivers covering regular motorway miles. In mycarcheck.com data, this exact 2.0 HDi version has appeared in 136 checks, covering 43 distinct VINs: a useful, though not huge, sample. Recorded cars averaged 84,000 miles and around 4,000 miles a year, with about 2.4 previous keepers. The average private-sale valuation was £400, a snapshot rather than a guaranteed asking price. Its economical diesel and air conditioning helped the 406 compete with the Ford Mondeo and Vauxhall Vectra. Comfortable on longer journeys, this older saloon suits commuters and families seeking space on a budget, but buyers should check its condition and service history carefully.
