Just watched a youtube video showing how to add vehicles, It looks like things may have changed as I can find a the vehicles folder as shown in vid. So if I download a zip file of a new car where do i put it. The how to add mods explanation does not work for me. Alpha 0.9 steam edition on a PC
After downloading a mod from here, place it in documents\beamng\mods. That's it. Don't unpack it or anything.
