While the car's basic mechanics is decent, I'd recommend not using the colors on the top left; "basic" colors. That way, you can pick any color in the other parts of the color picker, giving you free opportunities for color diversity. You also don't need to make the glass, glass. Instead of using the glass material, just keep it default material and color it a shade of blue (again, not the ones on the top left).

You should also uncheck the "Draw Borders" box on all objects (unless its a minor detail, like the gas cover or the door border).

Thanks for commenting, i will try making it better next time
