I decided to start modeling the car's dashboard, I will also model the door linings, but I am using the model in the second link as a base, it is not ready and I am in the learning phase, but I am happy with the result.
For now I only made the top part, I really don't know if this type of modeling using another model as a base is allowed, but it was the way I found at the moment.
On the bright side, it will be lowpoly, better to put in the game.
