The PEUGEOT 407 (2004-11) 4DR SALOON 1.6 HDI 110 X-LINE is a mid-sized, four-door family saloon, aimed at buyers wanting more space and comfort than a small hatchback without stepping up to an SUV. In the UK used-car market, it sits among affordable older diesel saloons, offering a practical alternative to Ford Mondeo, Vauxhall Vectra and Volkswagen Passat. mycarcheck.com records 12 look-ups covering six different VINs, a modest sample rather than a broad reliability verdict. Those checks show an average private-sale value of £900, average recorded mileage of 107,000 miles and annual use of about 4,000 miles. The cars checked had averaged 5.5 previous keepers, so history deserves close attention. The 1.6 HDi suits commuting and longer trips, with diesel economy and a roomy cabin making this 407 a sensible choice for couples or families. Distinctive styling and a comfortable ride set it apart, but age and upkeep matter most.
