M50d is a great car to live with, however as mentioned the engine is brutal
And if you're not about out right performance then stick with the 40d.
I try and drive it in comfort mode most of the time but it does rev quite freely and it's very easy to speed too often. In Eco mode it's exceptionally torquey and will pull hard and shift up quickly stopping the urgency of the motor somewhat. It's a great car but M50d is a bit over kill in my opinion but then what do I know my wife's getting her SQ5 on Friday and no way is her car going to have more power than mine
