Mechanically this car is wonderful. I went from a Dodge Charge w/ a V6 to the WRX and it is a night a day driving experience. Shifts are smooth and easy to navigate acceleration is more than adaquate and I've gotten pretty decent gas milage (21.5).
Two complaints, the stereo is terrible. The car is light and obviously is doing w/o on some sound insulation but that's not what bothers me. If you're going to save weight by not having that then make the stereo adaquate to compensate. It doesn't.
The leather on my new car was not installed properly. There was slack in the leather on portions of the passenger side seats. Stitching was good, but they left too much leather on the sections.
Quality of leather.
Higher quality speakers
Stereo/AC controls look a little cheap for the price of the car. Not enough to make it an issue, but they could do better
Assembly of the leather seating needs to be tighter.
