The thing is... I only need a coupe, in terms of passenger accommodation. Two main people, with occaisional rear jumpseat use.
As long as I can open the back part of the car wider than a few inches, and load some occaisional cargo items onto a load floor with the rear seats folded flat, that is also enough cargo space for me... otherwise I'd rent a pickup truck for a few hours, or something.
I actually do want a Grand Touring Coupe, with AWD capability, and suspension travel.
If I wanted 5-7 passenger seating, and more cargo space, I would go for X3 over X4, or otherwise X5 over X6, and get the full boxy 5-door.
That is why I think BMW X4 and X6 should dispense with the rear tandem doors, and just be versatile all-road liftback coupes, and not even try to be pseudo-sedans.
The only reason I consider XV Crosstrek or Forester, is because there is no availability of a 3-door All-road 3-door coupe comparable to it, or an AWD low-height coupe, either.
