The BMW 6 SERIES (2007-10) 650I 2DR CONVERTIBLE 4.8 AUTO is a premium four-seat convertible aimed at buyers wanting open-air comfort and a powerful grand-touring feel rather than everyday practicality. In the UK used market, it sits above ordinary family cars, competing with luxury drop-tops such as the Mercedes-Benz CLK and Jaguar XK. mycarcheck.com has recorded eight look-ups covering four different VINs, so this is a modest sample rather than a definitive picture. Across those checks, the average private-sale valuation was £6,700, recorded mileage averaged 107,000 miles, and annual mileage averaged 4,000. Vehicles had an average of just over six previous keepers, suggesting ownership histories deserve a careful check. Best for couples or enthusiasts wanting a weekend cruiser, it is less suited to budget-conscious drivers needing rear-seat space. Its V8, styling and folding roof make it distinctive; against smaller convertibles, it feels luxurious and effortless, though running costs are higher.
