The BMW 3 SERIES CONVERTIBLE (2007-14) 335I 2DR CONVERTIBLE 3.0 306 SE HIGHLINE DCT AUTO7 is a premium, four-seat drop-top rather than a practical family hatchback. It brings 3 Series saloon comfort and a powered folding roof to UK buyers wanting open-air motoring with more pace and polish than an ordinary compact convertible. Mycarcheck.com has six look-ups covering three distinct VINs, so these figures are useful indications, not a broad market survey. Across those checks, average private-sale value was £3,800, average recorded mileage 109,000, and average annual mileage was 1,000 miles. Average previous keepers stood at three. Its strong six-cylinder performance and automatic gearbox make it an engaging weekend car or comfortable long-distance companion, best for couples or small households happy to trade rear-seat access and boot space for sunshine motoring. Against rivals such as the Audi A5 Cabriolet, the 335i stands out for lively acceleration and BMW handling.
