The BMW 5 SERIES (2007-10) 520D 4DR SALOON 2.0 163 M SPORT STEP AUTO6 is a large, premium four-door diesel saloon, aimed at buyers wanting more space and comfort than a family hatchback. In the UK, it sits in the executive-car class, alongside the Mercedes-Benz E-Class and Audi A6, with a smart, sporty M Sport look and confident motorway presence too. Its 520d diesel engine and automatic gearbox make it well suited to commuting, longer journeys and regular travel, while the roomy cabin and boot can work for families. M Sport trim gives it a more purposeful appearance and engaging road manners without losing the comfort expected of an executive saloon. mycarcheck.com records show 779 look-ups covering 254 distinct VINs, a useful snapshot of interest. The average private-sale value is £2,200, with average recorded mileage of 158,000 and annual mileage of 7,000. Checks also show around 6.7 previous keepers on average, so reviewing each car’s history is especially important before buying.
