You seem to be confused. --- Post updated --- I got the links mixed up. --- Post updated --- here's the right one https://www.beamng.com/threads/buick-roadmaster-vers-1-1.14796/
say you want an audi r8 mod, so you go to the audi section in the list to see if there is one you see it says "audi r8", all you do is click on the text and it directs you to the audi r8 mod thread and then you just download the file, put it in your mod folder etc etc
THANK YOU for all the hard work! Just as a suggestion, it would be great to have an expandable (like the spoiler one) that enlists the additional mods by update. I want to try all the new stuff, and sometimes I lose track of what's new.
