The BMW 5 SERIES (2007-10) 540I 4DR SALOON 4.0 306 M SPORT is a large, premium four-door saloon, sitting above mainstream family cars in the UK market. It blends executive comfort with a powerful petrol engine and the sportier M Sport look, making it a distinctive alternative to an Audi A6 or Mercedes-Benz E-Class. It suits drivers who want a comfortable car with room for passengers and luggage, yet enjoy overtaking. The M Sport trim gives it a purposeful appearance, while the cabin and ride make longer journeys easier. This V8-powered 540i is best for experienced drivers prepared for higher running costs than an ordinary family saloon. Mycarcheck.com records 11 look-ups across three VINs, a small sample. The checks show an average private-sale value of £3,300, 109,000 miles and around 2,000 miles driven yearly, with about 2.5 previous keepers.
