The PEUGEOT 406 (1996-04) 4DR SALOON 2.0 EXECUTIVE AC SN is a spacious four-door family saloon from Peugeot’s mainstream range. It was for buyers wanting more comfort and room than a hatchback. In the UK used-car market, it competes with traditional saloons such as the Ford Mondeo and Vauxhall Vectra. This Executive version’s air conditioning and roomy cabin suit family journeys, commuting and relaxed longer trips. Mycarcheck.com records four checks across four cars, so the sample is limited. Average recorded mileage is 102,000, with 2.5 previous keepers and average annual mileage of 1,000 miles. Average private sale value was only £200. The 2.0-litre petrol Executive is best viewed as a comfortable, well-equipped older saloon rather than a modern economy choice; condition and service history matter greatly at this age. Its composed ride and roomy interior made the 406 a respected long-distance family car, offering a more understated alternative to sportier rivals.
