The BMW 3 SERIES CONVERTIBLE (2007-14) 335I 2DR CONVERTIBLE 3.0 306 M SPORT AUTO is a premium, four-seat, two-door convertible: a more powerful, sportier take on the executive drop-top, rather than a practical family hatchback. It suits sunny-day drives, weekend trips and buyers wanting open-air motoring with everyday comfort, though rear-seat access and boot space are less convenient than in a saloon. mycarcheck.com has recorded 1,053 look-ups covering 240 different VINs, giving a useful snapshot of interest. Its checks show an average private-sale valuation of £4,600 and average recorded mileage of 92,000 miles; typical annual mileage is about 3,000 miles. The average keeper count is around 6.7, so check each car’s history and condition carefully, as individual examples can vary. The 335i’s strong, smooth performance and M Sport styling make it more engaging than many Audi A4 or Mercedes CLK rivals, while its folding roof delivers a distinctive all-season grand-touring feel.
