it is also possible to use a static Car , in such a case if you do not use any other Program just wanna do it in Poser go to the grouping Tool after you loaded the Car. now check if the car is already grouped ! Check if the Groups would match your idea of movable parts like Door steering Wheel Wheels etc. in case that it is not grouped you will need to do it manually.

first create a new group in the list for wheel ex. rFrontWheel NO SPACES now paint a few Polygons , then go to Modify grow click grow until the whole wheel is marked red. Do this steps for every Wheel and parts you want to have articulated. Make sure that the Marked polygons for every new group correspond with the Part that you need. You do this until all polygons are filled checking if you have non-grouped -faces.

When done with all parts you can click Spawn Props , it will create for every grouped part a new Prop ! now you can delete the static car that you used to get the new Props. this is an easy beginner way to get the needed Props that you can now use to build your figure like I explained above.

Note: sometimes you want to have parts that will not work by using the grow tool in such a case you will have to paint the polygons manually. try the options Grow shrink mirror , or add materials in groups these help sometimes to work faster. the more you use that little tool the better you will get in creating Figures.
