The BMW 3 SERIES COUPE (2006-13) 320D 2DR COUPE 2.0 177 M SPORT AUTO is a premium two-door diesel coupe, offering a sportier alternative to a family hatchback. In the UK used-car market, it competes with the Audi A5 and Mercedes-Benz C-Class Coupe, combining smart styling with everyday usability. Mycarcheck.com has recorded 1,202 look-ups covering 454 different VINs, a substantial sample. Checks show an average recorded mileage of 129,000 miles, around 8,000 miles annually, and nearly six previous keepers; the average private-sale valuation is £3,100. These figures offer useful context, but each car’s history and condition can differ. The automatic gearbox and diesel engine suit longer commutes, while M Sport trim brings purposeful styling and an engaging feel. It best suits couples or drivers wanting a comfortable, stylish daily car rather than maximum rear-seat space. Against rivals, its appeal to used-car buyers is the blend of premium image, pace and usability.
