Hey Redbony, good looking cars you posted so far! I am hoping to create a new car soon(NFMWaster here btw), but I don't know what to make whether should it be a racer car or a waster car. Nice seeing your cars! See you around!
And hey, there is a great application in helping you to create your own cars without the hassle of entering rows of coordinates into the code editor. The application is called Blender. You can find the download link here: http://www.blender.org/download/get-blender/
And here is a link to a tutorial to help you get started...
Hahah, right now. The Crusher is probably easily the scariest car in-game when I use it as an AI. Holy crap, he shows up out of nowhere to ram into you and bash you apart. Really scary car I made so far.
