The BMW 5 SERIES (2003-07) 520D 4DR SALOON 2.0 AUTO is an executive car: a premium-feeling alternative to mainstream family saloons, rather than a hatchback or city car. Its automatic gearbox and roomy cabin make it appealing for longer journeys, business travel and commuting, while the boot and rear seats can also suit a small family. It is best for buyers wanting refinement and space in an older used car. In mycarcheck.com data, this model has had 7 look-ups covering 3 different VINs, so the figures offer a small snapshot rather than a market-wide picture. The average private-sale valuation was £1,500, with an average recorded mileage of 144,000 miles and annual mileage of 4,000. Checks showed an average of nearly six previous keepers, a useful reminder to review each car’s history and condition carefully. The 520d is known for blending relaxed motorway manners with better fuel economy than many larger petrol rivals. Its understated styling and premium badge remain appealing, though age and upkeep matter more than reputation alone.
