Bought it last night. Was a little disappointed there's no mods yet but I guess it might be too early for that.
Also, expected the graphics to scale a little better, but I may be just missing a couple things in the settings. Hopefully when I install my GTX 680 tonight I won't have to worry about that at all.
Can't wait for more cars to be added! Haven't been this excited about playing a racing game since GT4.
