The BMW 5 SERIES (2003-07) 540I 4DR SALOON 4.0 M SPORT AUTO is a premium four-door executive saloon, aimed at buyers wanting more space and comfort than a hatchback. Its M Sport trim adds sportier styling, while the V8-powered 540i sits near the performance end of the 5 Series range. mycarcheck.com has recorded 97 look-ups covering 26 distinct VINs, a snapshot, though not a huge sample. Checks show an average private-sale valuation of £2,000 and average recorded mileage of 125,000 miles. The cars average 4,000 miles a year and nearly five previous keepers, suggesting many are occasional-use or enthusiast-owned cars. Best suited to experienced drivers seeking a long-distance car with smooth performance, it can handle family duties, but running costs and fuel use are higher than with smaller-engined rivals. Against executive saloons such as the Mercedes-Benz E-Class and Audi A6, the 540i stands out for its engaging drive and character.
