The front window is pretty simple, but there're some "handles" that make it rotate. What you should do this time is start from a box and extrudge or move some faces.
The second most difficult part is creating the tyre. I used mainly cyllinders or tubes. It's also good to build something behind the wheel in order not to look "empty".
For me, the biggest part of the modelling is done, but we still have some little details to add.
So we've done the modelling, isn't he pretty :)
Texturing
The texturing is very simple when we make a studio photo, because there's no dirt and the car looks like new. Here are the settings that I set to my materials, I'm using vray as a renderer.
Chrome Settings 1
Chrome Settings 2

Carpaint Settings 1

Carpaint Settings 2

Carpaint Settings 3
Glass Material Settings
Lighting
I used some kind of studio lighting. I put Vray Plane Light right above the car, and moved the pivot somewhere in the car, so I easily copied them around the object. I put one infront, and 2 at each side. The colors are something very special for the scene, I set them light blue, pure white, and yellow. Maybe it's not the best desicion but the result is quite satisfying. So the scene looked like this:
Rendering
My renderer is vray and I can say that it's fast, easy to set and, of course, shows very good results. My render settings are:

Final Touches
If you don't like the colours or the contrast - there's always Photoshop :)
Conclusion
The modelling and the texturing parts were very easy. The render was very slow but maybe pretty good. If you have something to add or ask me about the model or the tutorial, send me feedback @ eveni.pavlov90@gmail.com . I hope my advices were understandable and easy to follow, see ya!
