40d, 50i or m50d?
I'm going to order a new X6 soon and can't decide on which model to choose between 40d, 50i and m50d.
40d is the most economical choice.
50i sounds best but will probably cost 2 liters per 10km.
50d is better looking and will feel more special but is at least 12000 euros more expensive.
Anyone drive all of these and care to share their thoughts?
