I bought my beetle used a couple of years ago. to my surprise, the car doesn't have an "engine guard" aka undertray. I guess some bonehead left it off.

My dilemma is that I know this is causing me to use more fuel than I'd like. I'm wondering if getting a factory one used would be the way to go? would that even offer enough improvement, or should I just make something myself?

thanks
