This is a project that started in early 2010, when there was no “Cycles” to make renders with blender. The intention was to learn to can deal with the new interface of Blender 2.5 and learn from the great blender teacher Jonathan Williamson.
In this link you can access the video series which shows how to model the porch:

I've added some pieces to the model to make it look more sporty
Blender community always makes things easier. And looking on the internet for how can rig a car I found a specific addon for this task.
Car rig:

This is a lot like rigify addon (included in blender), but for cars So I use it and I made some small modifications, for me it would be easier to animate.
So you can download it and do whatever you want with it (No commercial,remember is a fan art). No have textures etc.. just the car , the Rig, and and some other stuff for create the picture.(for render this picture , turn off "simplify" for see subdivisions)
On The next video , you can see the Rig in action , and how to reuse it in other cars ( sorry my english )
