I don't think the cargo capacity argument really holds water. I drive a Volvo V60 wagon which has trunk space of 23.2 cubic feet. When it was in the shop, I had a loaner XC60, and I could noticeably feel that the trunk space was about the same, despite the vehicle sitting considerably taller.

Sure enough, the XC60 crossover has a trunk space of 22.4 cubic feet.

It's the same trunk, just higher off the ground, which to me makes it less useful to me: more lifting to get stuff in, harder to rummage through items (eg camping pantry), much more difficult to access my roof box.
