BMW 6-Series Coupe (2011 - 2018) 640d M Sport 2d Auto Owner Review

First diesel engine for me and it's surprisingly smooth as well as being economical given the performance. It's a big and heavy car though and you can feel the weight when pressing on or when braking heavily. Rear legroom is poor if you are behind a tall driver and ride gets crashy and unsettled on 20 inch rims on potholed roads. Otherwise the ride is good, it's refined and the engine gives out plenty of smooth power. Had to have the EGR replaced which was leaking coolant into the engine - BMW assisted with goodwill payment - car was out of warranty. Servicing costs not too bad though tyres expensive.
