The BMW 5 SERIES (2007-10) 520D 4DR SALOON 2.0 177 M SPORT is a large, premium four-door saloon, sitting above family hatchbacks and alongside executive rivals such as the Audi A6 and Mercedes-Benz E-Class. It suits drivers wanting space and comfort without choosing an SUV, while its M Sport styling adds presence. mycarcheck.com records show 1,446 checks covering 571 different VINs, a substantial sample of interest in this model. Checked cars averaged £2,600 in private-sale value and 140,000 miles, with about 7,000 miles driven annually and nearly five previous keepers. These figures describe checked examples, not a guarantee for any individual car. The 520d suits commuters and families seeking a roomy cabin, useful boot and relaxed long-distance travel. Its diesel engine offers everyday pace with relatively modest fuel use, while M Sport styling gives the saloon a sportier presence. This used BMW 5 Series is a polished alternative to similarly aged executive rivals.
