I just pre-ordered my copy of Gran Turismo from Gamestop. Apparently, depending on where you pre-order from dictates which bonus car you get. Here is the list from Sony...
Amazon.com: 2002 Enzo Ferrari Giallo Yellow
GameStop: 2009 Bugatti Veyron Black
Gamecrazy: 1974 Lamborghini Countach Arancio Orange
Best Buy: 2008 Citreon by GTbyCitreon Yellow
...I can't wait for this game to come out. I've been waiting since october of 2005 for this damn game to come out and this is either going to make or break the PSP for me. Depending on how good this game is will decide if I'm going to abandon my PSP's and move on to another platform/device, most likely an iPod touch.
