New mod maker help

So yes, I'm yet another mod maker who has joined this community, and I need help from actual mod makers to tell me on how to make a mod
Me with 2 of my friends has decided to make a custom BMW x Death note (anime) mod pack, which contains multiple BMWs.
One of my friend knows how to model and stuff and has been a part of this community, and is going to help me with the model making
The other guy is going to help me acquire the model from games or websites so that it can be made into a beamng mod
Our first project is going to be a bmw z3 m coupe with a custom logo (the one like my pfp) and possibly a custom livery
Neither of us really know that well about modding as the last time the modder friend made a mod was like 2017 and I'm pretty sure things have changed from that time.
So I'm making this thread to get help from the people (in form of videos or other threads) which could potentially help us in making this mod

Also, is using models from games (like forza or nfs) allowed?

 

I don't really know much about mod making so I'll stay out of that, but for the last question that you asked, I'm pretty sure you can use models from other games as long as you say that it has been taken from the game and not just claim it your own
