The PEUGEOT 407 (2004-11) 4DR SALOON 2.0 HDI 136 SPORT AUTO NAV is a roomy four-door family saloon, not a hatchback or SUV. In the UK’s large-car class, it suits buyers wanting motorway comfort and rear-seat space. This diesel automatic adds navigation, making the 407 a well-equipped option for journeys. Mycarcheck.com records 12 look-ups covering seven distinct VINs, offering a snapshot rather than a market-wide survey. Across these checks, the average private-sale valuation was £1,000, average recorded mileage 137,000 miles and annual mileage 9,000 miles. Cars averaged just over four previous keepers, so check each vehicle’s history and condition carefully. Best for commuters or families wanting relaxed trips, it is less handy in city streets than a small hatchback. Distinctive styling, a comfortable ride and navigation are appealing strengths. Against Ford Mondeo and Volkswagen Passat rivals, it is a less common alternative; check service history and automatic operation before buying.
