I have only owned the vehicle for a few days, but it is incredibly solid and quite fun to drive. Going from a Z28 to a four-cylinder was a bit daunting, but the car feels spritely for 170 ponies. Controls are well laid-out and easy to figure out, and the car responds as though it is meant to be driven. After test-driving a few vehicles (Corolla, Civic, etc) the Subaru was by far the most fun and felt like the best value for my dollar, especially with the full-time All Wheel Drive. The stereo is a bit tinny (base model), but can be easily upgraded. Absolutely opt for the auxiliary-input if you get the base model for MP3 connectivity - it's a blast!
Downshifting and blipping the throttle around corners plants the car firmly - good road manners under any driving conditions, and better than projected fuel economy (I've been getting ~25 combined city/highway and the car is still being broken in) - expecting 30+ with average driving.
Base speakers need upgrading; rear drum brakes on base model are solid, but I'd like to see 4 wheel disc. VDC (traction control) now standard on 09, so I'll curb that one! :)
