Well first of all you are in the wrong section of the Forums, this part is for mods not questions. The right section should be Troubleshooting: Bugs, Questions and Support And the answer to your question: It is not that simple to make car mods for beamng. It takes years of experience in Blender which is a 3d modelling software just to make the models themselves and then you will need some sort of software for textures like subtance painter. And then if you want to even get all of that in game you will need to learn jbeam and how stuff in beamng works
