The PEUGEOT 407 (2004-11) 3DR COUPE 2.7 HDI V6 SPORT AUTO is a large, two-door diesel coupé, offering a relaxed, distinctive alternative to a family hatchback. In the UK used-car market it is a niche choice: focused on comfortable long-distance travel and style rather than practicality, and often cross-shopped with older executive coupés. mycarcheck.com has seen 15 look-ups covering 10 different VINs, so the figures offer a snapshot rather than a broad market survey. Recorded cars averaged £1,700 in private-sale value, 136,000 miles and about 5.7 previous keepers; average annual mileage was 17,000. These figures can help set expectations, but each car’s history and condition matter. Its V6 diesel and automatic gearbox suit motorway journeys, while the Sport trim and striking coupé shape give it more presence than many mainstream rivals. It best suits drivers wanting an affordable, comfortable grand-tourer, rather than low-cost town motoring or maximum family space.
