The BMW 5 SERIES (2003-07) 530D 5DR TOURING 3.0D 231 SE is a large, premium diesel estate, offering executive-car comfort with the load space and everyday usefulness British buyers often seek. It sits above mainstream family cars, appealing to drivers wanting a more refined long-distance car without choosing an SUV. Mycarcheck.com records 29 look-ups covering 16 different VINs, so the sample is useful but modest. Those checks show an average recorded mileage of 170,000 miles, around 7,000 miles a year, and about 4.3 previous keepers. The average private-sale valuation was £1,600; these are observed figures, not a guide to any individual car’s condition or current worth. The roomy Touring suits families, commuters and motorway travellers needing luggage space, comfort and confident overtaking. Its six-cylinder diesel delivers a relaxed, capable feel, while premium appeal and practicality make it an alternative to the Audi A6 Avant and Mercedes-Benz E-Class.
