Not really a wagon...or a HB...somewhere in between, IMO.
Closest by comparison to the 3-series Touring.

Most dimensions fairly close until you get to the overall height and ground clearance. So if one wants to insist that's it's a "wagon"...then it's a tall wagon. Conversely, if one wants to call it an "SAV", then it's a rather short SAV.
Either way, I'm really liking mine. I will hit 100 miles today!
FWIW, all things being equal, it should cost a minimal amount to manufacture a car with higher ground clearance. Different springs and dampers and maybe a few other drivetrain and steering components. Differerent, however, doesn't always equate to more $$$.
