BMW 640d M Sport Gran Coupe finished in Metallic Grey with 20" M Sport alloy wheels. 80,000 miles, full service history and substantial engine work completed in 2026. For us, the 640d Gran Coupe is one of BMW's most underrated cars. Beautiful proportions, a fantastic driving position and the effortless performance of the 3.0-litre twin-turbo diesel straight-six. A proper long-distance GT that still feels like a BMW to drive. What makes this particular example especially interesting is the maintenance. In 2026, the car benefited from a new timing chain and substantial bottom-end engine work, with invoices to support it. These are exactly the sort of major mechanical jobs buyers worry about on a used performance diesel, so having this work already completed offers considerable peace of mind. It's also had upgraded brake discs and pads fitted, meaning further money has been spent in the right places. Visually, the car has been tastefully enhanced with an OEM+ approach. Lowered suspension, wheel spacers and a subtle exterior styling kit give it a much more purposeful stance without spoiling the original design. The specification is excellent too, with Head-Up Display, Digital Instrument Cluster and Extended Leather making the cabin feel every bit as special as the exterior.
