The BMW 5 SERIES (2007-10) 520D 4DR SALOON 2.0 163 SE STEP AUTO6 is a large, premium four-door family saloon, sitting above mainstream models such as the Ford Mondeo and alongside executive rivals like the Audi A6 and Mercedes-Benz E-Class. Its understated styling and automatic gearbox suit drivers wanting comfort and space for everyday journeys and longer trips, with extra refinement too. Mycarcheck.com records show 609 look-ups covering 296 distinct VINs, a substantial sample of checking activity. The average private-sale valuation is £2,100, while checked cars averaged 154,000 miles and around 10,000 miles a year. They had just over five previous keepers on average, so condition and service history deserve careful attention. This 520d is best suited to commuters, couples and families who want a roomy car for motorway travel, rather than a city runabout. The diesel engine offers long-distance economy, and the 5 Series is known for a comfortable, confident drive; compare age, upkeep and equipment with rivals before buying.
