Well 3D max is different than photo shop. In 3D you cannot think of it as a picture anymore and have to think of it as a physical object. You get 4 view ports to work in and you have to use every single view to make sure your model looks good from any side.
You start off from a small box or a flat 2D plane which than you need to extend and work your way into making it 3D. You can youtube just stuff like 3D max and there should be a lot of posts regarding how it looks like and how people make things in it. Sorry about my writing I am a bit busy so typing a bit fast.
Edit: Here is another car I did for a cleint recenly. He wanted his ford to be mainly stock but with some crazy custom wheels.
Also, a colorful render will be out soon.
