The BMW 5 SERIES (2003-07) 545I 4DR SALOON 4.4 SPORT SMG AUTO is a large, premium four-door saloon, aimed at buyers wanting executive-car comfort rather than a hatchback or SUV. In the UK used market, it sits among rivals such as the Mercedes-Benz E-Class and Audi A6, with a sporty, driver-focused image. Its 4.4-litre V8 and SMG automatic-style transmission give it strong, smooth performance, while the Sport trim adds a purposeful feel. It is best suited to experienced drivers, long-distance commuters and households wanting a comfortable car for business or family journeys. Running costs and fuel use are likely higher than smaller saloons, so budget accordingly. mycarcheck.com records eight look-ups, but these relate to one distinct VIN, so figures are a small snapshot, not a market-wide guide.
