As I first started playing Forza I didn't notice that my car was auto-tuned until I bought my second car. I noticed the class rating was changing on every car that I looked at. Why have tuning available if the car is going to tune for you. WTF? The tuning aspect was one of the things that I LOVED about all the other Forza games. That being taken from me and being dangled in front of my face makes me give this game its low mark. Everything else was great; graphics, sound, control; but let me tune my own car for Christ sake.
