The 2007 Subaru Impreza is definitely an improvement over the 2001 Subaru Impreza I traded. Less body roll, more responsive steering, nicer interior. The transmission feels a bit more refined, and it actually has a synchro for first gear (2001 didn't). The clutch is more forgiving than the 2001, I can shift smoother. The engine sounds and feels more refined as well. And this thing is a blast to drive. Once you're on boost, this thing really goes. I have no regrets with my decision.
Good power in the lower rpm, especially for a turbo car, auto-dim mirror, automatic climate control, responsive steering, corners flatter (minimal body roll).
Shifting is still notchy, but better than in the past; the seats could be better padded (a little firm), my glove box rattles a little.
