Costs & verdict
Everyday costs, plus how reliable and safe it is
The M8 isn’t cheap, costing well over £100,000 for the coupé, while the convertible is even pricier. If you’re weighing up your options, a Porsche 911 or Mercedes S560 Coupé or Cabriolet is a lot less money, but then the M8 is small beer next to the cost of an Aston Martin DB11 or Bentley Continental GT.
And if you have an eye for investments, the 911 will retain much more of its value after three years than the M8. The DB11 will have lost over half its value by then, while the S-Class’s value will have plummeted.
On the plus side, it is marvellously well equipped, with 20in alloy wheels, keyless entry, a leather interior, a carbon-fibre roof and heated seats as just some of the highlights. The optional extras list is eye-watering, some of them being bundled into the several packs you can choose from.
The M8 hasn’t been crash tested by Euro NCAP, but you do get a range of safety aids as standard. These include automatic emergency braking (AEB) and lane-keeping assistance, while the convertible comes with roll-over protection.
Meanwhile, you can expect middling reliability: BMW came 21st out of a possible 31 manufacturers in the 2019 What Car? Reliability Survey. That was above Mercedes and Porsche, but below Audi. Aston Martin wasn't included.
