This is one of my favorite cars. I modified it so that you can open the door with Numpad 7 and enabled suspension height adjustment (rodlength) since most of the examples I found online are pretty slammed). Amazing car, incredible model. I love the animated shifter when accellerating. Awesome.
If you are looking for an idea, a second version with wider Superlight rims pushed out to the corners and slightly flared fenders, like the real world 906 car, would be pretty sweet.
