No, it is not. CongressDJ repeated one of my first "wishes", having a trunk height setting based on the location.Already existing: see owner's manual "Adjusting Liftgate Opening Height"
e.g. when I park in the single-garage in our seaside residence, I'd like to avoid having to stop the trunk hitting the swinging metal door without having to remember to use the "Adjusting Liftgate Opening Height" you mentioned.
Have to say this became less relevant with the Highland, because of a significant "downgrade" in the opening. The previous M3 had a significantly wider opening. But still, they have it on the S/X, so why not on the 3/Y?
