For It has a well-insulated metal roof that you can raise or lower while the car is moving. The cabin is nicely finished and standard equipment is generous.

Against The handling isn’t that agile and petrol models have high running costs. The rear seats are best for children.

The BMW 4 Series Convertible isn’t the most spacious four-seat cabriolet, but it does enough of the basics to ensure it should be on your shortlist if you’re after upmarket open-top motoring.

Buyer's notes

Target Price team says:

The 4 Series Convertible is an appealing rival for Mercedes’ E-Class Cabriolet. The 420d is the only one that makes much sense, though, because the other versions are petrols that are more expensive to run – due to relatively poor fuel economy and high company car tax bills – or more powerful diesels that cost quite a lot more to buy.

Equally, we’d struggle to look past entry-level SE specification and justify the extra expense of the other trim levels. SE comes with all-round parking sensors, climate control, heated leather seats and a 6.5-inch infotainment screen, so it has more than enough of the basics.

The good news is that regardless of which version you go for, the 4 Series Convertible has a smooth-operating, well-insulated metal roof. It opens and closes in 20 seconds, and can be operated at speeds of up to 11mph.

Just remember that the slightly more expensive E-Class Cabriolet does a better job of being a refined four-seat drop-top.
