My daily driver has been a 2009 base model Impreza like that for almost 10 years, so clearly I like the car.
The good:
* The most comfortable, composed ride of any car I've ever driven, including Oldsmobiles, Cadillacs, and Buicks.
* The AWD is beyond reproach. I've never even seen the traction control come on, even when I was the last car let through before the road closed. Very rarely I'll take a hard right turn onto wet pavement, feel the front wheels slip about a quarter turn, and then feel the rear wheels do the same. Very cool.
* Brutally simple. Still has the normal 4-speed auto. Not much gadgetry to break. Relatively big, low-stress N/A motor.
* Not just reliable, but durable. The interior has held up. Trim parts don't scuff or fall off.
* Seats, controls, etc. fit me well.
The bad:
* City mileage is just plain poor. I don't care about this myself.
* The base stereo is inadequate. The under-seat subwoofer makes it more than adequate.
* Not a fast car in most regimes. Good for a slap in the back when the light turns green, and a decent passer, but kind of slow otherwise.
* Pretty noisy by today's standards.
* Rolls a bit more than, say, an Altima.
* Pretty wimpy window motors? I guess I'm running out of things now.
