What should I be paying?
It’ll be a doddle to own. Such a big engine will be exceedingly understressed in day-to-day life, and while BMW claims mpg in the mid 20s, we reckon you’ll better it when you’re not waking up those turbos too much. Mind, expect the number to freefall when you do prod them into life. But forays into the orange and red bits of the rev counter will forever be stymied by pesky speed limits; away from an autobahn this car does inevitably feel a bit caged. But then the M5 is far from the only culprit in that regard.
Should you spec that mega, 19 grand options package? ‘Sup to you. We’d resist, but the carbon-ceramic brakes (£7,995 with the 190mph limiter thrown in for free) are a must, while the £1,000 laser lights will come in handy when you inevitably slip out late at night to unleash this thing free of traffic.
We lived with an M5 in the Top Gear Garage for almost a year, post-facelift. You can read how we got on with it right here.
