It doesn't took that much time to turn 2 image into B-leveled 3D logo in Z-modeler.

1. First, layer the background image of the logo in TGA
2. Use FACE tool to create and trace it over the logo.
3. Once done then duplicate into 2 face planes where the 2nd planes shift back to create gap between two logo then combine (UNION) as one object.
4. In Vertices mode bridge two planes via stack of faces to create B-level like object.
5. Detached the B-leveled surface and other required surface to create proper vertex shading, the NORMAL the surface to create proper shading/render.
6. Done, Delete the 2nd planes to remove access poly.

So there we go a 3D logo for our new car.
