The BMW 5 SERIES (2003-07) 520I 4DR SALOON 2.2 SPORT AUTO is a roomy, premium four-door saloon, positioned above ordinary family cars in the UK used market. It pairs a petrol engine with an automatic gearbox and Sport trim, offering comfortable cruising with a more engaging feel than a basic runabout. With generous cabin space and a boot, this 5 Series can handle family trips, commuting and longer motorway journeys; it is best for drivers who value refinement and space over low running costs. Mycarcheck.com recorded 43 look-ups across 11 distinct VINs, a modest sample rather than a complete market picture. Check data puts average private-sale value at £1,500, average recorded mileage at 125,000 and annual mileage at 4,000; sampled cars had about five and a half previous keepers. Against Audi A6 and Mercedes-Benz E-Class rivals, the BMW offers a driver-focused feel, mixing comfort and sportier character, but overall condition matters.
