The BMW 3 SERIES CONVERTIBLE (2007-14) 330I 2DR CONVERTIBLE 3.0 272 SE HIGHLINE STEP AUTO6 is a premium four-seat, two-door convertible, offering an open-air alternative to executive saloons and family hatchbacks. Its folding hard roof gives coupé-like security when closed and lets you enjoy sunny-day motoring with the roof down. With its 3.0-litre petrol engine and automatic gearbox, the 330i blends lively acceleration with relaxed cruising, making it appealing for weekend drives and touring. It suits couples or small households more than families needing easy rear-seat access or ample luggage space. Compared with the Audi A4 Cabriolet and Mercedes-Benz CLK, the BMW is prized for its balanced, engaging drive. mycarcheck.com has recorded 16 look-ups covering three distinct VINs, so this is a small snapshot rather than a market-wide sample. Those checks show an average private-sale valuation of £3,100, mileage of 82,000 and 4.3 previous keepers; average annual mileage is 2,000.
