Personally i loved it;
It had some really neat little touches, like the birds flying, the windows - and when they was up how the outside sounds become more muffled.
I didnt like the fact your car never got damaged though, the damage on other cars was good but yours was left mint.
I found it harder to control then PGR especially when going fast it was a lot harder to turn the cars, certainly on my buy list though.
Even with AA i thought it looked pretty good too, some of the camera angles were nice, and the incar view was nicely done - especially when you can change how high and close you sit!
I really like this so far
