Only things i can complain about are the lack of an interior view, lack of a Fiero, and there is an error when i try to upload my photos. Other than that Ive been having lots of fun with it. No lag, glitches or crashes on my first gen 360.
Edit: Well even though it said error apparently it still uploaded my picture. I played it for a few hours the day I got it then went to bed. This is currently the fastest car I own. My suped up 944
