Costs & verdict
Everyday costs, plus how reliable and safe it is
The 8 Series sits at the premium end of the convertible market, so it's not cheap, but it's not bad value for money relative to its rivals. Even the top-end M850i, for example, is significantly cheaper than the equivalent S-Class Cabriolet and Bentley Continental GT Convertible, while the 840d massively undercuts the Porsche 911 Cabriolet.
You won’t need to add many options, either, but you can still go to town adding extras if you want to. All models have two-zone climate control, leather seats, power-folding door mirrors and heated seats. You can also add heated armrests, a heated steering wheel and much, much more. The M850i adds a sports exhaust system, lightweight 20in wheels and the M Sport differential, for that added cornering traction. All models also get a wind deflector and BMW’s Air Collars, which are integrated into the front head restraints and provide a stream of heated air to warm your neck when the roof is down.
