Car Controller Asset?

The title says it all basically, I need a car controller asset much like the character controller asset, the character controller asset wasn’t anything too amazing but played a great part in making a basic ground for you to develop, this is exactly what I want but with a car asset.

I want to import it just like the character asset, and drag and drop it onto the scene and develop it like i would with the character controller.

Im on Mac OS X and running Unity 4.x

Thanks for any help,
Ash

1.) Upgrade to Unity 5.x
2.) Go Assets → Import Package → Vehicles → Car
