The BMW 5 SERIES (2007-10) 520D 4DR SALOON 2.0 177 SE AUTO is a premium four-door saloon for buyers seeking more space and comfort than a family hatchback. In the UK's executive-car class, it rivals the Mercedes-Benz E-Class and Audi A6, with understated styling suited to business trips and family duties. With its diesel engine and automatic gearbox, this 520d is well suited to longer commutes and motorway journeys, while the SE trim offers a comfortable, refined feel. It is a sensible choice for professionals or families who value a roomy cabin and relaxed progress, though its size and running costs may be less appealing for mainly short, urban trips. mycarcheck.com has logged 1,717 look-ups across 704 different VINs, a substantial sample.
