This YouTube video was posted by a guy in an Alfa Romeo at O'Reilly Raceway park during the afternoon session in the 2007 One Lap of America. He's racing a Blue C5 Z06 with a Pfadt sticker on the back. It sure looks like Patrick and the DCZ. I like the part where Patrick blows off the Alfa when it pulls along side on one of the straights. I also like the part earlier in the video where the Alfa spins after passing Patrick and gets to watch the DCZ drive on by.
