The BMW 6 SERIES (2004-07) 630I 2DR CONVERTIBLE 3.0 is a large, premium four-seat convertible, sitting above ordinary family cars in the UK used market. Its long, elegant shape and folding roof make it a relaxed grand-tourer for sunny-day drives, rather than a budget runabout or practical SUV. mycarcheck.com recorded 35 look-ups covering 17 different VINs, a useful snapshot, though not a huge sample. Checks show an average private-sale valuation of £3,300 and average recorded mileage of 117,000 miles; annual mileage averages just 4,000. The cars have had around six previous keepers on average, so check each car’s history and condition carefully. It suits couples and enthusiasts seeking open-air comfort and a special feel. Limited rear space and running costs make it less suited to families or commuting. Against the Mercedes-Benz CLK and Audi A4 Cabriolet, the 630i offers elegant styling and relaxed long-distance driving. Check service history before buying.
