In 3D Design today, we had a tutorial on box modeling. We made a basic car which with many features from the modify tool. We used editable mesh to modify the edges, vertices's, polygons etc... When the car shapes were in place we used other modifying tools like taper / squeeze to make the car how we want it.

After developing the box model car, we used the colour modifier to make everything look realistic, as you can see I have used a blue for the body, grey for the chrome and light transparent blue for the windows.
