The BMW 5 SERIES (2003-07) 520D 4DR SALOON 2.0 SE AUTO is a spacious, premium four-door saloon aimed at buyers wanting more comfort and presence than a family hatchback. In the UK used-car market, it sits among executive cars, traditionally competing with the Audi A6 and Mercedes-Benz E-Class. Its understated design still feels suitably smart. mycarcheck.com records 668 look-ups across 306 different VINs, giving a useful snapshot of cars checked. The average private-sale valuation is £1,400, while recorded mileage averages 159,000 miles and annual use about 9,000 miles. Checks show an average of just over six previous keepers, so review each car’s history carefully. The automatic transmission and comfortable cabin make it well suited to motorway commuting, travel and family journeys, especially for drivers who value a composed, spacious ride. Compared with mainstream saloons, it offers a more upmarket feel; at this age, condition and maintenance matter than badge appeal.
