The BMW 3 SERIES CONVERTIBLE (2007-14) 325D 2DR CONVERTIBLE 3.0 197 M SPORT HIGHLINE STEP AUTO6 is a premium four-seat, two-door convertible: an open-top alternative to an executive saloon. In the UK used market, it sits above mainstream cabriolets, offering BMW appeal and a more substantial, sporting feel than smaller soft-tops. Mycarcheck.com records 227 look-ups covering 58 different VINs, a useful sample of buyer interest. Checks show an average private-sale valuation of £5,300, average recorded mileage of 98,000 miles and about 5,000 miles driven annually. The average keeper count is just over five, so check service history and ownership details carefully. Best suited to couples or small households, it makes touring enjoyable; the diesel and automatic suit longer journeys, while M Sport styling adds appeal. Against Audi A5 and Mercedes CLK rivals, it offers driving enjoyment and open-air character, but rear access is limited. Check roof operation and running costs before buying.
