Costs & verdict
Everyday costs, plus how reliable and safe it is
Prices for the BMW 4 Series Convertible start slightly above the Audi A5 Cabriolet, but that’s partly because the 4 Series is available only in relatively high-end trims. Indeed, if you’re looking at equivalently specced versions of the 4 Series, A5 and Mercedes C-Class Cabriolet, they all have very similar brochure prices.
Always check to see how much you can save over at our New Car Buying section because all three cars are often available with significant discounts.
The 4 Series received a full five-star rating after being safety tested by Euro NCAP. It did better in all areas than its closest five-star rival, the C-Class Cabriolet, which is impressive given that the 4 Series was tested under the latest and most stringent regime yet. Its high scores were partly thanks to the equipment it packs to help prevent you from having a collision, including automatic emergency braking (AEB) and lane-departure warning.
Buyers can also add the optional Driving Assistant Professional Pack (which comes as part of the Technology Plus Pack). That includes adaptive cruise control, a more advanced lane-keeping assistance system, a front cross-traffic alert system (this detects traffic that's about to pass in front of you when you're waiting at a T-junction) and automatic speed limit assistance.
