The BMW 5 SERIES (2003-07) 520D 4DR SALOON 2.0 is a large, premium four-door diesel saloon, sitting above mainstream family cars in the UK market. It offers a more spacious, comfortable alternative to a hatchback, with a useful boot for everyday journeys and longer trips. The 2.0 diesel suits commuters, company-car drivers and families who regularly cover distance and want a relaxed, refined drive. Against rivals such as the Audi A6 and Mercedes-Benz E-Class, the 5 Series is known for combining comfort with an engaging feel behind the wheel. As an older premium car, condition and service history matter more than the badge alone. Mycarcheck.com has recorded 19 look-ups across 12 distinct VINs, so its figures offer a useful snapshot rather than a broad used-car market survey. In that sample, average recorded mileage is 173,000, annual mileage 12,000, and previous keepers about 7.5. The average private-sale valuation is £1,200; check each car’s history and condition carefully.
