This car is painted without any texture, UV, and baking. I use only the vertex paint information. All color get information from vertex position and orientation. So your model can be very thin in memory size.
So I create this car in 3d for further development of “Vertex color” system in Blender. For creating new tools and features like layer system, alpha-transparency support in the viewport, vertex color masking.

You can download blend file and test “Vertex color”.

But you also need a custom build of Blender with “vertex color” node from here:
