The PEUGEOT 407 (2004-11) 4DR SALOON 2.0 HDI 136 EU4 SE NAV is a roomy, four-door family saloon, sitting in the larger mainstream class rather than the city-car or hatchback market. Its diesel engine and navigation-equipped SE trim made it a comfortable choice for longer journeys and everyday use too. mycarcheck.com has recorded 426 look-ups covering 266 distinct VINs, a substantial sample. Records show an average private-sale valuation of £1,000 and mileage of 121,000 miles; annual mileage averages 8,000, and cars had nearly four previous keepers. Treat these figures as context, not a guarantee for any individual car when shopping. It suits commuters and families wanting a relaxed, spacious motorway companion, especially at a modest used-car price. Against Ford Mondeo and Vauxhall Vectra saloons, the 407 is remembered for distinctive styling and a comfortable, well-equipped cabin; check service history and condition carefully, as age and mileage matter more than reputation.
