Are there any vehicle wrapper tutorials that aren't outdated or incomplete?

I have spent so many hours of my day searching for a tutorial on implementing vehicle physics, but it seems that every one of them is either incomplete or incompatible with the current version of Blender’s game engine. Could someone show or redirect me to a decent tutorial on how to implement the vehicle wrapper in a current version of Blender?

EDIT: I found a tutorial buried in a thread pretty deep in this forum that works with the latest version of Blender. Hope that this helps some people out who are searching for this.
