My neighbor came over the other day to help out with my deck and he pointed something out on my car that I didn't notice before. There's a small plastic piece fastened on by some sort of snap on the driver's side door near the rear wheel well. The passenger side does not have this piece at all for some reason and now that I noticed it, it looks really weird. What is it and what can I do about it? Thanks

 

if u go on ebay im sure you can find the peice there etheir called side skirts or exterior trim peices
