The BMW 3 SERIES COUPE (2006-13) 330D 231 2DR COUPE 3.0 231 SE 6SPD is a premium two-door diesel coupe, a sleek used-car alternative to UK family saloons and hatchbacks. Long-distance comfort and useful rear seats give it more versatility than a strict sports car, though access is less convenient. On mycarcheck.com, this version has prompted 510 checks covering 153 different VINs, offering a useful snapshot of buyer interest. The checks show an average private-sale valuation of £2,400 and average recorded mileage of 145,000 miles. These are observed figures, not a guarantee of what any individual car is worth or has travelled. An average 6.15 previous keepers and 6,000 miles yearly make ownership and service history worth checking carefully. It suits commuters and couples seeking relaxed long-distance pace, refinement and more punch than mainstream coupes. Against Audi A5 and Mercedes CLK rivals, its appeal is engaging handling and a premium everyday feel.
