The BMW 5 SERIES (2003-07) 550I 4DR SALOON 4.8 SE AUTO is a large, premium UK four-door executive saloon, sitting above family cars in comfort and performance. Its spacious cabin and automatic gearbox make it suited to long-distance commuting, business travel and comfortable family journeys, rather than tight city parking or budget motoring. The 4.8-litre V8 gives this 550i a notably strong, smooth drive, while SE specification focuses on relaxed comfort. It feels more special and powerful than many mainstream saloons, and competes with large-engined Mercedes-Benz E-Class and Audi A6 models. Running costs and fuel use are likely to be higher than smaller-engined alternatives, so it best suits buyers who value refinement and performance. mycarcheck.com recorded 23 look-ups covering eight distinct VINs, so the sample is limited but offers a useful snapshot: average mileage was 104,000 miles, annual mileage 3,000, and average keeper count nearly four. Average private-sale valuation was £2,100.
