I have the physics model for a 4WD Beetle for Richard Burns Rally working here on my computer. Makes a change sometimes from the Subaru's extreme understeery characteristics, and it's noticeably more better balanced & poised when pushed hard into corners. Definitely more fun to drive.
Only problem is that I gave up trying to make the 3D model for it on Z-modeler
In any case somebody already made a 3D 1303S for the Rally Trophy computer sim on PC.
With z-modeler (or Max) you can manipulate that model to look however you wish (obviously). Huge whaletail took a few hours to morph.
Only problem with the model is the guy who made it wont let you do what you want with it. As far as he's concerned the model is his intellectual property, so i can't even post pictures here of it here. Or use it for my Beetle in Richard Burns Rally
But here's a link to the original car in action

There was a video of this 1303 on the Nurbergring but I cant find it anymore.
