COOL! Thanks for those Eric... I'm absolutely loving Grid at the moment, more than Gran Tris Prologue. If any one else has got the game, then try and get yourself a Steering Wheel, makes the game so much more enjoyable to play.
This game sucks,the handling is horrible,back to gt5
thanks Eric
got it last week.. nice game, great graphic, may need a little improvement, but it's totally enjoyable.. anw, thanks for the cheat man..
