Question for "Sell your BeamNG cars"

Hello all, I'm new and I don't know some things.
In the thread "Sell your BeamNG cars", when I sell/buy something, what should I do after? How do I pay the price of the cars? And when some people buy my cars, how do they pay?

 

You do not actually pay money, you just pretend to pay.

 

It´s roleplay. You dont have to spend real money
You make some picture in the game.
Post them there. Say something about the car you sell
wait or "buy" another car from other person
Nothing with real money

 

When I buy a car that is a mod, the seller can give me the link of the mod...

 

Sir this forum section is for help and support with the game, not on how to roleplay in a forum thread, should have just asked in the thread

 

Thank you for your time.
@SixSixSevenSeven In the forum main page there is written "Questions and Support; ask questions and get answers", so I imagined that this section was for all questions.
