The BMW 4 SERIES CONVERTIBLE (2017-20) 430I 2DR CONVERTIBLE 2.0 SS 252 EU6 M SPORT AUTO8 is a premium four-seat convertible for drivers wanting open-air motoring with everyday refinement. In the UK, it sits above mainstream drop-tops, appealing to buyers considering an Audi A5 Cabriolet or Mercedes C-Class Cabriolet. With its 2.0-litre petrol engine, smooth eight-speed automatic and sporty M Sport look, the 430i offers brisk, polished cruising. The folding roof adds appeal, while four seats suit couples, commuters and small families willing to trade rear space for open-air enjoyment. Mycarcheck.com has recorded 529 look-ups across 214 distinct VINs, a substantial checking sample. Its data shows average mileage of 33,000, annual mileage of 7,000 and around 1.4 previous keepers; the average private-sale valuation is £21,000. These figures offer context, but condition, history and local market prices still matter when comparing a used BMW 4 Series Convertible before making an offer.
