I'm in no position to judge the transmission issue, since I don't (at present) own a Subaru.
The crosswind reactions are perfectly predictable, given the Subaru's height and profile. This is not a particularly ærodynamic vehicle, nor was it designed as such. It's a utility somewhere between a wagon and a SUV. Comparing it to your Mini Cooper is like comparing the ærodynamics of a tennis shoe to a barn door.
We're currently driving a vehicle that had a sticker of $41K (in 2004!), and doesn't have a wood-trimmed steering wheel. (2004 SAAB 9-5 Arc Wagon, the dash looks like wood, but I doubt that it ever saw a tree) No SAAB has ever had a wood-trimmed steering wheel. The cars you mention all cost, for the most part, significantly more than a Subaru.
