The BMW 5 SERIES (2003-07) 520D 5DR TOURING 2.0 SE is a five-door diesel estate, combining the 5 Series’ executive-car feel with useful room for passengers and luggage. In the UK used-car market, it sits among larger premium family wagons, rather than everyday hatchbacks or SUVs. The Touring body makes it practical for work, holidays and busy family life. Mycarcheck.com records 337 look-ups covering 172 different VINs, giving a useful snapshot of cars checked. Those checks show an average recorded mileage of 181,000, around 9,000 miles a year, and about five to six previous keepers. The average private-sale valuation is £1,300, so condition and history matter greatly. Best suited to drivers wanting comfort, carrying space and a composed drive, its diesel engine suits regular journeys. It rivals the Audi A6 Avant and Mercedes-Benz E-Class estate, offering a practical alternative. Given the age and high mileages seen in checks, review condition and history carefully.
