BMW 5 SERIES (2003-07) 523I 4DR SALOON 2.5 SE AUTO
Buyer's Guide & Data from our Checks
The BMW 5 SERIES (2003-07) 523I 4DR SALOON 2.5 SE AUTO is a spacious petrol executive saloon for buyers seeking comfort and refinement. In the UK used-car market, it competes with premium four-doors such as the Mercedes-Benz E-Class and Audi A6, rather than hatchbacks or compact runabouts.
The 2.5-litre six-cylinder engine and automatic gearbox suit relaxed commuting, motorway journeys and family trips, with a roomy cabin and boot for daily use. SE trim has a comfort-focused feel, and the 523i delivers smoother, more composed travel than many ordinary saloons. At this age, condition and running costs need careful attention.
