Unsolved No textures. American 80's Fullsize Series 2.1

Hi. I need a little help. I don't have any textures on my car. I only have them on the rims and on a few details. I do not know what to do. I am sending you a screenshot so you can see what it looks like. I've verified the game files,I clear cache and I checked whether any modification affects it, but unfortunately not. I hope someone will be able to help me with this.

 

Make sure you have the addon AND repo version active at the same time

 

I found the problem. As you wrote, I checked if I have not installed the main modification and it turned out that I actually do not. Silly me thanks for the help.

 

had the same problem once too. glad you found out man. hope u have fun with the olds!
