Just a note on your last images :)
Seems the botom front of the car is not very aerodynamic ?
Seems like a "snowplough" or "bulldozer" :)
Not very good fo the fluent air flow and CX ?
Am I right ?

Hi Pilou,

I made some changes at the front,and if I find something else I will change it.I just practice my design and nurbs skills.Maybe at the end I will put it on the 3dmarket,and sell as printable 3d object.

And maybe the 2 last holes will be closed by glasses' lights! ;)
