The BMW 5 SERIES (2003-07) 520D 5DR TOURING 2.0 M SPORT AUTO is a premium five-door estate, combining executive-car comfort with useful load space. In the UK used market, it sits above mainstream family estates, appealing to drivers who want a more refined, well-equipped alternative without giving up everyday practicality. mycarcheck.com checks show 68 look-ups covering 39 distinct VINs, a useful but modest snapshot of interest. The average private-sale valuation is £1,600, while the average recorded mileage is 178,000 miles. Cars averaged around 8,000 miles a year and just over six previous keepers, so condition and history deserve careful checking. Well suited to commuting, long trips and family life, its estate body carries luggage and holiday kit, while M Sport trim adds a sportier look and feel. Compared with the Audi A6 Avant and Mercedes-Benz E-Class estate, it is engaging; given its age, check condition and history carefully before buying.
