Used BMW 8 Series Gran Coupe for sale: everything you need to know

The BMW 8 Series Gran Coupe might make the most sense out of any BMW 8 Series. You lose little in the styling department to the coupe and convertible models, but gain four-door practicality and much more rear-seat room than the oddly cramped coupe.

It’s otherwise very similar, from the driving experience to the engines and trim levels available, and still feels special as a result. It’s no sports car, but it makes for a fine grand tourer - and one that’s a lot more affordable when you buy used.

The Gran Coupe goes head-to-head with cars like the Audi A7 Sportback, Mercedes-Benz CLS (and the AMG GT 4 Door), and the Porsche Panamera. Each car has its own strengths and unique style, so there are no bad choices in this little corner of the market.

Should you buy a BMW 8 Series Gran Coupe?

If you like the idea of a BMW 8 Series but fear the two-door layout and cramped rear quarters might limit its usability, then the 8 Series Gran Coupe could be the car to fix that. It adds an extra pair of doors and liberates a little more room for rear-seat passengers, however occasional they might be, but still looks like a sophisticated grand tourer.

It still drives like one too - from behind the wheel, you’d struggle to know there was more space behind you. The interior layout is grand, well-built, and driver-focused, and the driving position low-slung and comfortable. There really is more space in the back too - it’s no 7 Series, nor even 5 Series in this respect, but it’s more accommodating than the two-door car.

Engine choice is the same, which means six-cylinder petrol and diesels depending on the year, a V8 petrol in the form of the M850i, and an M8 at the top of the range. The sixes suit the 8 Series down to the ground though - they’re smooth and respectably frugal, and still have a real turn of pace.

The 8 Series isn’t quite a sports car to drive, but it’s impressively able for its weight and size - at five metres long, it’s up there with luxury saloons in length. It has luxury car-style refinement too, though remember it will also come with luxury car running costs.

Potential alternatives to the 8 Series Gran Coupe include the Audi A7 Sportback, Mercedes-Benz CLS, and Porsche Panamera. Each is more spacious than the 8 Series Gran Coupe, but the BMW’s driving experience is slightly sharper than the Audi and Mercedes, if not quite the Porsche.

What’s the best used BMW 8 Series Gran Coupe model to buy?

Both six-cylinder models are the ones to pick here. The 840d suits the 8 Series Gran Coupe’s grand-touring brief perfectly, being powerful, smooth, and returning impressive economy figures, though the rear-wheel drive 840i sDrive is probably the sweet spot as a driving machine - the engine is more tuneful than the M850i’s V8 and it feels a little nimbler too, with less weight to lug around. M Sport trim is standard across the range, but BMW offers numerous options and packages, so some used models may be better equipped than others.

What used BMW 8 Series Gran Coupe trim levels are available?

All Gran Coupe models come in a variation of M Sport trim, with the M850i matching them for equipment but adding a few unique touches.

• The BMW 8 Series Gran Coupe M Sport gets 20-inch alloy wheels, an M aerodynamics package, adaptive LED headlights, an Iconic Glow illuminated kidney grille, automatic tailgate, digital driver and infotainment displays and a head-up display, Merino leather trim, heated front seats, Harman Kardon audio, four-zone climate control, ambient lighting, adaptive suspension, M Sport brakes, and cruise control with a brake function.
• The BMW 8 Series Gran Coupe M850i features largely the same equipment as M Sport models, but can be distinguished by a different 20-inch wheel design and a dark gloss exterior details package.

Used BMW 8 Series Gran Coupe road tax

How much is it to insure a BMW 8 Series Gran Coupe?

An 840i sDrive kicks off the range with an insurance group rating of 44, and it only climbs from there - the 840d xDrive is in group 47 and the M850i xDrive in group 49, out of a maximum 50. That starting point is higher than the group 40 of an Audi A7, but lower than the group 49 of both the Mercedes CLS and Porsche Panamera.
