BMW M8 Gran Coupe review

It’s a bit new, so there’s no real data on the GC as yet, but seeing as this is basically an M5 it should be as easy to own as a 340i. There are plenty of dealers happy to extract your cash for servicing, and support is widely available. There’s also a whiff of deals to be done even with brand-spanking new cars, so a bit of haggling might well bring this slice of German muscle down a few grand. In terms of the practicalities, it should manage just over 25mpg, but pushed it’ll drop to single figures, and driven like you have sore feet will manage more than 30. One long and restrained trip managed 33-34mpg, so that 4.4 can be efficient. It’s a bit boring getting that out of it though. It’s also a 625bhp, 100k+ super-saloon, so insurance is unlikely to be cheap no matter how old/rural you are, and depreciation on these things is not traditionally very kind, so there’s a definite argument for waiting for someone else to take the hit and picking up a pre-loved tidy one in 5000 miles’ time.
