Why should you put away the Grand Theft Auto IV disc for a few days to play the GRID demo on the PS3 and Xbox 360? Because if you get the fastest lap in Time Attack mode, you have the chance to win a real car; a Ford Mustang GT-R. The five people with the fastest times will be flown to San Francisco for the GRID launch event and once there, they have the chance to compete to win an eBay Motors-branded Ford Mustang GT-R.
You have to actually go to Codemasters’s official GRID community site and enter your times manually though, where they will be authenticated and ranked on the online leaderboard. You have until May 25th to get those times in though, so you better start racing now. I wish I had more time to devote to this because I want that Mustang.
