Blender vehicle creation

Well this is my car so far: http://www.beamng.com/threads/2932-BMW-850Ci but im not sure what to do now. Do I need to make it for example so the doors are seperate from the model itself, the same goes for the chassix, boot engine, etc??

 

All parts need to be separate from each other, just like a real car. You can snoop around Gabe's meshes to see how things are made, and the standards to which they should be made.

 

I was actually going to start a thread about that, how can I import it to blender?

 

Thanks. By the way great job on the BMW
