Should you buy a BMW 8 Series Convertible?

Yes. Considering the number of roles the BMW 8 Series Convertible is expected to fulfil – wafty open-top cruiser, hunkered down sports car and luxurious grand tourer, it would be easy to cast off as a jack-of-all-trades. And yet it works.

While the 8 Series Convertible doesn’t hold up to the Porsche 911 Cabriolet in outright driving stakes, nor feel as special as the Aston Martin DB11 Volante, it does offer a satisfying amount of both experiences, albeit at the expense of outright driving feel and feedback, due to the large amount of active chassis tech needed to rein in the car’s size and weight.

Still, as you can’t drive those two cars at the same time, the 8 Series Convertible represents a luxurious, but entertaining way to tick off the miles on a long journey. The entry-level models will provide the best-value experience, as the more powerful engines command such a higher price in comparison that it’s difficult to see what else you get for the money. Especially when the M850i and M8 versions break the £100,000 barrier.

The M850i is great as a grand tourer, offering muscular pace and long-distance comfort, but you’d want a dose more speciality in the cabin than what’s on offer. With the ability to option one up to £120,000, it’s quite difficult to justify.

The flagship M8 Competition doesn't live up to the sporting side of things either – this is still a portly BMW, meaning it’s too heavy and wayward for bona fide fans to see this as a ‘proper M car’. Get the coupe version if you want more finesse, but the convertible is almost even more entertaining with the absence of it.

The Bentley Continental GT still manages the performance-luxury mix better, even if the more agile M8 feels like it’s done some exercise down the gym, but the former is more opulent and offers an even more dizzying level of pace. If you simply want luxury, however, the Mercedes-Benz S-Class Cabriolet still rules the class for just effortless, luxurious pace for four.
