The PEUGEOT 406 (1996-04) 4DR SALOON 2.0 HDI 110 SE AUTO AC SN is a four-door, medium-sized family saloon, offering a more traditional alternative to a hatchback or SUV. Its diesel engine and automatic gearbox suit relaxed journeys, while air conditioning and SE trim add everyday comfort. In the UK used-car market, it sits among affordable older family cars, rather than premium executive models. It works well for families and commuters wanting a spacious cabin and an easy-going drive, especially for regular longer trips. Compared with Ford Mondeo, Vauxhall Vectra and Volkswagen Passat rivals, the 406 is known for comfortable ride, understated styling and economical HDi diesel performance; the automatic version favours convenience over sporty feel. As with any older car, condition and service history matter more than reputation. mycarcheck.com logs five checks across two VINs; recorded averages in a small dataset: 99,000 miles, 8,000 yearly, £500 value, 3.4 keepers.
