I knew exactly what to expect when buying this car, and it was everything I ever asked for. Read all the reviews and youtube test drives of this car before buying.
Handling is sporty, suspension is stiff but comfortable for a daily driver (which mine is, I drive 35,000kms annually) Interior quality is great and looks nice for a base model car.
Gas mileage is good. Better than rated. I'm getting 28-29MPG driving somewhat aggressive, and have reached 33MPG, doing mostly highway and shifting below 5k rpm's, using only 91 octane.
Now for my favorite part. The K20 engine and trans. It LOVES high rpm's, and the 6spd shifter paired with limited slip diff is one of the best I've ever experienced; SUPER smooth and precise. Acceleration is below avg compared to rivals such as the Mazdaspeed3 or Cobalt SS, but I'm happy with it.
Also mods are endless; tons of possibilities if you're into that.
Downsides: Paint chips and scratches easily. Back seats are tight for leg and head room, but still functional for short trips. Runs on 91octane if that's a problem for those gas saving misers out there.
