The BMW 5 SERIES (2003-07) 545I 4DR SALOON 4.4 SPORT AUTO is a four-door executive saloon, sitting near the top of the used-car market for comfort and performance rather than low-cost motoring. Its smooth automatic gearbox and powerful 4.4-litre petrol engine give it a special feel beyond everyday family transport. It suits drivers seeking refinement for journeys, motorway commuting or family trips, especially those who enjoy acceleration. Running costs are higher than smaller saloons, making it less suited to first-time drivers or anyone prioritising fuel savings. Against the Mercedes-Benz E-Class and Audi A6, it is known for confident, involving driving. Mycarcheck.com records 142 look-ups across 20 distinct VINs, a useful snapshot rather than a full census. Checks show an average private-sale valuation of £1,700, recorded mileage of 139,000 and 9,000 miles a year; vehicles averaged 7.6 previous keepers, so review each car’s history and condition carefully before making a decision.
