You aren't gonna find one here in the Beamng webpage. There are some mods from third party websites, but they are either meshslaps(no modified crash physics) or contain viruses.
Create your own! Personally I want to drive a Flying Spur in-game. I've been in them many times IRL and they are very nice.
im sure if they knew even remotely how to do so they wouldn't have made a thread lol even then, teaching them from ground zero wouldnt be easy either.
