The BMW 5 SERIES (2003-07) 520D 5DR TOURING 2.0 AUTO is a spacious, premium diesel estate, aimed at drivers wanting executive-car comfort with the practicality of a large boot. In the UK used-car market, it sits above mainstream family estates, offering a more upmarket alternative to models such as the Ford Mondeo Estate or Vauxhall Vectra Estate. Mycarcheck.com has recorded four look-ups covering two distinct VINs, so this is a small sample rather than a broad market picture. Those checks show an average private-sale valuation of £1,100 and average recorded mileage of 200,000 miles, with around 12,000 miles driven yearly and six previous keepers on average. These figures underline the importance of checking each car’s history and condition. The automatic suits traffic; diesel works well for commutes and family trips. Comfortable, spacious and refined beside rivals, the Touring appeals, but age and mileage make careful checks essential before buying.
