Whoa, tough crowd here
I have a feeling the roads are going to be beat up for a while so if "sport" isn't the primary driver for her I'd go for better clearance. I have an XV on order and having driven a few of them I can say that I think it's nicer to drive than the sport wagon. The ride is really similar, just a touch more firm, it has dramatically less body roll and the higher seating position is nice actually. If the extra weight slows the car down I challenge you to actually feel it, with the more crisp suspension and stiffer chassis (yes they did beef it a bit) the car is pretty snappy. Not fast for sure but it has a nice attitude.
