I found this game while browsing the Games for Windows Marketplace client. Normally it's $29.99 but only $7.48 if your interested in car racing.
You need to install Games for Windows client before you can purchase this game.

Bought this for $2 on Steam at Christmas, was hardly worth it then, can't imagine it being worth it now at twice the price.
