The BMW 5 SERIES (1996-03) 540I 4DR SALOON 4.4 PROTECTION AUTO is a premium four-door saloon in the executive-car class, for buyers wanting comfort and presence rather than an economical runabout. Its Protection designation marks a security-focused version, making this 540i more unusual than a BMW 5 Series. With a strong 4.4-litre petrol engine and automatic gearbox, it is suited to relaxed long-distance travel and motorway cruising, with space for adults. It may appeal to drivers seeking a distinctive luxury saloon, though running costs and age make it less suitable for first-time drivers or budgets. Mycarcheck records 32 look-ups covering 14 different VINs, a modest sample; the average private-sale valuation is £2,000. Recorded cars averaged 164,000 miles, around 4,000 miles a year, and 5.4 previous keepers. Against Mercedes-Benz E-Class and Audi A6 rivals, the 540i stands out for its powerful, comfortable character, but check each car’s history and condition carefully.
