The BMW 4 SERIES CONVERTIBLE (2013-18) 420I 2DR CONVERTIBLE 2.0 SS 184 EU6 SPORT AUTO8 is a four-seat, two-door convertible positioned above hatchbacks and alongside open-top rivals. Its folding roof offers year-round usefulness with open-air appeal, while the automatic gearbox and petrol engine make it relaxed for longer trips, too. Mycarcheck.com has recorded nine look-ups covering seven distinct VINs, so this is a small snapshot rather than a broad reliability verdict. Those checks show an average private-sale valuation of £14,000, 50,000 miles recorded and around 5,000 miles driven annually. Cars checked had averaged about 2.4 previous keepers in this sample. Best suited to couples or drivers wanting a commuter that can double as a weekend escape car, it offers more polish and rear-seat flexibility than many two-seat roadsters. The 420i balances lively performance with sensible petrol use; as with any used convertible, inspect roof operation and service history before buying.
