Alright, gonna be making my first car mod with the blender jbeam plugin and the nodebeam editor. Need to know what to do.
I would strongly advise to make a prop first before making a car, to get the hang of it. You should read the documentation (no excuses that it's too long or something), then analyze some vanilla props and try to make a new one based on them. After that you can make some parts for another car to better understand how Jbeam works in terms of vehicles. After making a few small mods like this, maybe you will be ready to make a car. It can take a few months to learn Jbeam even before you start, but it's better for you to figure out simple stuff first so you won't be overwhelmed.
I'd really have been making props as i also had the idea of starting small, I was gonna think about having a cube with wheels
