Try this free package of car paints.  There are some chrome materials in there too. I use them all the time.

They are used in the material room.  Select the part of the body and double click the material in the library to apply it.

Here is another tutorial on chrome too for you to try.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
