The BMW 6 SERIES (2007-10) 630I 2DR CONVERTIBLE 3.0 272 SPORT AUTO is a premium four-seat convertible, sitting above BMW saloons as a stylish grand-tourer, with a refined cabin and plenty of presence. Its folding roof and six-cylinder petrol engine make it an indulgent choice for relaxed open-air driving rather than low-cost motoring. mycarcheck.com records 384 look-ups covering 130 different VINs, a useful sample of interest in this older model. Checks show an average private-sale valuation of £5,900 and average recorded mileage of 104,000 miles; typical annual use is 5,000 miles. The cars checked have averaged just over five previous keepers, so history deserves careful review. Best suited to couples or drivers wanting a comfortable touring car, it offers a smooth drive and distinctive presence. Against the Mercedes CLK Cabriolet, the BMW feels more driver-focused, but running costs and limited rear space make it less practical than mainstream family cars.
