The BMW 5 SERIES (2010-13) 520D 5DR TOURING 2.0 DPF 184 M SPORT STEP AUTO8 is a premium executive estate: roomier and more practical than a saloon, but more composed than an SUV. It sits in the family-car market, offering a refined alternative to rivals such as the Audi A6 Avant and Mercedes-Benz E-Class Estate. Its 2.0-litre diesel engine and automatic gearbox suit long commutes and motorway journeys comfortably, while the Touring body gives families useful luggage space for holidays and shopping. M Sport trim adds a purposeful look and more engaging feel; the 520d balances brisk performance with sensible fuel use for everyday driving. mycarcheck.com checks recorded 111 look-ups across 55 distinct VINs, a useful snapshot of used examples.
