The BMW 3 SERIES CONVERTIBLE (2007-14) 335I 2DR CONVERTIBLE 3.0I 306 EU5 SPORT PLUS EDITION 6SPD is a four-seat convertible, offering a more involving alternative to mainstream family cars. Its six-speed manual gearbox and strong 3.0-litre petrol engine make it suited to buyers who want open-air motoring with performance, rather than a weekend cruiser. mycarcheck.com has recorded three look-ups for this model, covering one distinct VIN, so the figures are indicative rather than a broad market picture. Those checks show an average private-sale valuation of £10,300, average recorded mileage of 31,000 miles and around 1,000 miles driven annually; the average number of previous keepers is two. Against the Mercedes-Benz CLK and Audi A5 Cabriolet, the 335i stands out for lively performance and a driver-focused feel. It suits couples or small households wanting stylish open-air motoring, but running costs and rear-seat space may limit everyday family appeal. A folding roof brings flexibility.
