I have the special edition model. The stereo is awesome for stock. I bought the car with 75000 miles on it. It now has 105000. I havnt had any mechanical problems other than it is a 3 cranker starter, also the brakes (normal wear and tear), the fan blade burning out (easy to replace) and a pulley that is squawking (yet to replace but no real problems with it yet). I'm not sure of any mechanical problems if any the car had before i bought it. I have a lead foot and drive the car hard everyday and the car takes it and then some with ease.
The stereo, looks sporty and drives sporty for the most part. Fuel economy. huge trunk for its size. and again the stereo!
The head gasket and starter issues others have discussed. No aftermarket performance parts available.(not that it matters to most), slow acceleration. stupid cup holder placement. cramped engine bay.
