Which used BMW 6 Series coupe should I buy?
If you are planning on using your BMW 6 Series as it was intended – in other words, for long trips – then you should choose the diesel model. Its breadth of abilities makes it our recommended engine option.
If you do shorter journeys or you mostly drive in a big city, the 640i would be a suitable alternative, even if it does cost more to run.
We’d suggest sticking with SE trim, because it comes with all the equipment you really need.
Our favourite BMW 6 Series: 640d SE
