Mic has uploaded 10 brand new renders of all the cars done so far. Visit this thread to see them all Dynamic5.gamespy.com.
Before you click on it, a warning. There's over a Meg of images to download so if you're on a painfully slow connection it could take a while to get them all. While your at the forum, feel free to register and get posting.
Also, expect some screenshots of Silent Stunner's new map this weekend.
