The BMW 4 SERIES CONVERTIBLE (2017-20) 420I 2DR CONVERTIBLE 2.0 SS 184 EU6 SPORT PROFESSIONAL MEDIA 6SPD is a premium four-seat convertible for drivers seeking open-air motoring with comfort. In Britain, it sits above mainstream drop-tops, pairing styling and a quality cabin with a sportier feel than cars or soft-top rivals. mycarcheck.com recorded 20 checks covering 14 distinct VINs, a modest sample rather than a market-wide picture. Those cars averaged £14,900 in private-sale value, 45,000 miles and about 10,000 miles a year; recorded ownership averaged 1.45 previous keepers. These figures offer context, but an individual car’s condition and history matter most. The 420i suits couples, professionals and households wanting a commuter that can become a weekend escape car; rear seats are handy for passengers, not a large family. Its petrol engine and six-speed manual promise engaging driving, while the folding roof delivers the open-air appeal that sets this BMW apart.
