Just to confirm, you're working on fixing the fiat 500's key hole with the blinker and the bmw missing front seats?
My game crashes when I open the mod window. I tried launching my game with only this mod enabled and I've already cleared the cache. Here's the error if it helps: BeamNG 0.37.4.0 0x00000001
you just install it in your mods folder and load up a map then press the "esc" key then the [ key and it should bring up the menu to start it up
