The BMW 3 SERIES (2005-12) 320I 170 4DR SALOON 2.0I M SPORT AUTO is a compact executive saloon: a smart, four-door family car with a sportier image than an ordinary runabout. In the UK used-car market, it sits alongside the Audi A4 and Mercedes-Benz C-Class, offering a premium badge and a driver-focused feel. With 170 horsepower, a petrol engine and automatic gearbox, this M Sport version suits commuting, longer trips and family duties, while its comfortable cabin and composed road manners make everyday driving enjoyable. The saloon shape gives useful boot space, and M Sport styling adds a more purposeful look; it is best for buyers wanting comfort with a livelier edge. Mycarcheck.com records 211 look-ups across 95 VINs, a useful snapshot, not a census. Checked cars average 93,000 miles, 5,000 annually and 4.6 previous keepers; average private-sale value is £3,600. These figures set expectations, but condition and history matter.
