I tried a lot Add-On Gameconfig. for the 1.0.1180.2 Patch and no one was working for me so I decided to make one by myself. Currently I have over 600 Add-On Cars and my Game is not crashing.
Q: Why can't I use this mod?

A: Yes, but I suggest you try a clean install first.
Q: How do I install this mod?
A: Download the .rar file and extract it to your desktop. Then go to the [update] directory and run the installer.
Q: Why does my car not work?
A: If you are using a car from another mod, make sure you don't have that mod installed. If that is not the case, try running a clean install of the game and see if new cars are working for you.
