The BMW 6 SERIES (2004-07) 630I 2DR CONVERTIBLE 3.0 SPORT AUTO is a premium open-top grand touring car, designed for comfortable journeys and leisure with a sporty edge. In the UK used-car market, it sits above everyday family cars as a distinctive luxury convertible, rather than a practical hatchback or SUV. Mycarcheck.com records 942 look-ups across 331 distinct VINs, offering a substantial snapshot of buyer interest. Average private-sale value is £4,100, with 104,000 miles recorded and 4,000 average annual miles. Cars have had around six previous keepers, so check the example’s condition and history carefully before purchase; these are averages, not guarantees. The automatic 3.0-litre petrol engine and folding roof bring relaxed cruising and open-air enjoyment, but running costs exceed those of everyday cars. Best for couples or enthusiasts wanting a stylish weekend tourer rather than a budget commuter, the 630i rivals the Mercedes-Benz CLK, offering poised driving and distinctive BMW character.
