If you are looking for a luxurious four-door coupe sports car, the 840i would be a great pick. It drives like a thoroughbred rear-wheel-drive coupe, has an energetic and willing motor, and sitting in the cabin feels special. On the other hand, if you want a bit better cabin experience and more convenience and feel-good features, you may go for 840i Gran Coupe. If budget is not an issue and power performance is you priority, M8 Coupe would be a great choice. You may compare all its variants accordingly.Do take a test drive in order to get better clarity.
