if you did make this in 3ds max, try following this tutorial. I know its meant for animations but you can also use it with cars. (for your purpose). Add more lighting and make renders with high resolutions by going to render setup and changing it there. Another good ting to do is to change the material setting of the car to metal rather than the default Blinn, it will make it look more realistic when reflecting lights. Add more lights so you are able to see the car more. Use sky lights more than just random omni lights and make sure theyre no just white light since youre never gonna get a perfect white light, try using a bit of light orange light, not completely orange but a bit of orange in it so it doesnt look like boring old white. hopefully u will use this advice and improve your renders.

FAKE

Why does this look so fake to me?

You'll need a lot of lighting and background if you wanna make it better.

Shouldn't use a black background. Ever

Looks uhh... REALLY blurry. So blurry it looks almost pixelated. Also, learn to size your renders. 640x480 doesn't show off shit.

Looks blurry.
