However these vehicles got coined in the beginning, it's completely backwards. It makes much more sense to call the one which handles poorly, is very boxy, not as technically advanced roadwise, and sits high up a 'wagon'. And vehicle which is more fun to drive (sport), easier to handle in parking garages, easier to load a roof rack (utility), a SUV.
Somewhere on bimmerpost there's a M3 wagon someone converted. I'm totally baffled how someone would think it invokes a pedestrian, home maker image.
