Is it possible to have a super mod that is an extra 'blockland,' in wich you build cars like that, and then save them. the mod would do all of the scripting work. You would place a sit or stand or lie brick somewhere in the model, and add wheel bricks, or rocket bricks with a set forward direction. then the mod combines the bricks, creates the sitting places and wheels, and packages it along with the colors used and all other files needed. I am a noob so this is probabally not possible, but it sounds like it would work, with a TON of scripting...
thanks
