The BMW 5 SERIES (2003-07) 525I 5DR TOURING 2.5 M SPORT is a premium five-door estate, combining executive-car comfort with useful luggage space. In the UK used-car market it sits above mainstream family estates, appealing to drivers who want refinement and a more engaging feel without giving up everyday practicality. The 2.5-litre petrol engine and M Sport trim give this Touring a brisk, composed feel. Its roomy cabin and boot suit family trips, commuting and weekend gear. Against Audi and Mercedes estates it offers comfort and driver appeal, though smaller family cars may cost less to run in daily use.
