if you like driving your prix then keep it. i like driving mine because it will go through a ton of snow, it gets decent mileage, it is fairly fast for what it is, and fixing it is cheaper than any other car ive ever had.
This is why I haven't sold my car and bought something faster yet. I use it in the snow more than my F-150 and with a bit of mod time and money, I'll have it running 13's.
