The PEUGEOT 407 (2004-11) 4DR SALOON 2.2 HDI 170 SPORT is a roomy, four-door diesel family saloon, aimed at buyers wanting more space and comfort than a hatchback without moving to an SUV. In the UK used-car market, it sits among affordable mid-size executive-style alternatives to the Ford Mondeo, Vauxhall Vectra and Volkswagen Passat. mycarcheck.com has recorded 15 look-ups across 12 distinct VINs, so these figures offer a useful snapshot rather than a broad market survey. The average private-sale valuation is £1,200, with average recorded mileage of 164,000 miles, annual use of 5,000 miles and 4.8 previous keepers. That combination may suit shoppers prioritising low purchase cost, but makes checking condition and history especially important. Its distinctive styling and brisk diesel performance give it more personality than many sensible rivals, while the saloon boot suits luggage. It works best for longer commutes and family trips; check service records and condition.
