I want to try to get my head wrapped around Blender and make these (preferably sun/moonroof) but I want to know 3 things: 1. How do I put the car models in Blender? 2. Do these exist already?
You go to \Steam\steamapps\common\BeamNG.drive\content\vehicles\sbr.zip\vehicles\sbr & copy the sbr.DAE to somewhere on the desktop (for ease of access). Then you open Blender, Import -> Collada (.dae) -> search for the file on the desktop & import it. After that, you delete all the unnecessary meshes (models) & get working on the body mesh
