The BMW 4 SERIES CONVERTIBLE (2013-18) 420I 2DR CONVERTIBLE 2.0 SS 184 EU6 SPORT 6SPD is a premium four-seat convertible for drivers who want open-air motoring with more refinement than a basic car. In the UK used market, it sits between family cars and luxury tourers, combining styling with a folding roof and room for rear passengers, plus a well-finished cabin. mycarcheck.com has recorded 12 checks across seven different VINs, so the figures offer a useful snapshot rather than a broad market survey. Those checks show an average private-sale valuation of £14,300 and average recorded mileage of 42,000 miles. Average annual mileage is 3,000, while cars had about 1.6 previous keepers. The 420i Sport suits couples, commuters and weekend drivers, though families may find the rear seats tight. Its drive feels engaging, and the open roof distinguishes it from Audi A5 and Mercedes-Benz C-Class coupes, making it a choice for escapes.
