BMW 6 SERIES CONVERTIBLE (2015-18) 640I 2DR CONVERTIBLE 3.0 SS 320 EU6 M SPORT AUTO8
Buyer's Guide & Data from our Checks
BMW 6 SERIES CONVERTIBLE (2015-18) 640I 2DR CONVERTIBLE 3.0 SS 320 EU6 M SPORT AUTO8 is a premium four-seat open-top grand tourer, not a runabout. Its 3.0-litre petrol engine, M Sport styling and eight-speed automatic bring performance and relaxed cruising. In the UK, it occupies the luxury convertible niche.
Across 93 mycarcheck.com look-ups covering 30 different VINs, the average private-sale valuation was £21,600, with average mileage of 42,000 and annual use around 5,000 miles. Cars checked had about 1.7 previous keepers on average. These figures describe checked examples, not a guarantee of any individual car’s condition or value.
This BMW 640i suits drivers seeking roof-down weekends and comfortable long trips, with rear seats and boot space making it more practical than two-seat sports cars. It is less suited to family-duty than a saloon. Against the Mercedes E-Class Cabriolet, it stands out for lively performance, M Sport character and refined cruising.
A BMW 6 Series Convertible can hide outstanding finance, write-off damage, mileage discrepancies or theft history. Enter the reg now—skip the check and an expensive mistake could be yours.
