The PEUGEOT 407 (2004-11) 4DR SALOON 2.0 HDI 136 GT AUTO is a large four-door family saloon, offering more comfort and presence than a small hatchback. In the UK used market, it is an affordable older choice alongside the Ford Mondeo, Vauxhall Vectra and Volkswagen Passat in the same class. Mycarcheck.com has recorded eight checks covering seven distinct VINs, so its figures offer a snapshot rather than a market-wide verdict. Those records show an average private-sale valuation of £1,100, mileage around 141,000 and five previous keepers; average annual use is 10,000 miles. Treat these as context, not a price promise. With its diesel engine and automatic gearbox, the 407 suits commuting, motorway journeys and family duties, for drivers who value an easy, comfortable ride over sporty handling. The GT trim gives it an appealing, well-equipped feel, while its roomy saloon layout makes it a practical alternative to some estate cars.
