The BMW 6 SERIES (2007-10) 635D 2DR CONVERTIBLE 3.0 286 EDITION SPORT AUTO is a large, premium four-seat convertible aimed at buyers wanting open-air motoring with more comfort and presence than a roadster. In the UK used-car market, it sits among grand touring luxury cars rather than everyday budget convertibles. Mycarcheck.com records 24 look-ups across eight distinct VINs, a modest sample, so figures are a guide rather than a market-wide picture. The checks show an average private-sale valuation of £4,900 and mileage of 79,000; recorded annual use averages 2,000 miles, while cars have had about 4.6 previous keepers on average. Low mileage may indicate leisure use, making it suited to couples wanting a touring car rather than families needing practicality or drivers focused on low costs. Its diesel power, automatic gearbox and folding roof deliver relaxed cruising with brisk performance, helping the 635d stand apart from other luxury convertible rivals.
