They're decorative. If they made them out of pot metal or something like that instead of plastic,
1) They would weigh more, and every little thing on the car needs to be as light as possible in order to keep GM'* Corporate Average Fuel Economy rating as high as possible
2) They'd probably cost more to make
3) They'd have to be finished in some way, such as by painting, whereas plastic ones can be molded in color, and will be done as soon as they pop out of the mold.
