So whats the advantage to having one of theses if they didnt feel the need to put them on later cars, and did all cars come with that plastic undertray under the radiator section?

Depending on time, aluminum is more expensive than plastic. There's other properties, but I imagine aluminum is a little more expensive now-a-days.

Reduces the drag coefficient. Probably by only .01 or .02 though.
