Well I came out from this lady's house today & noticed that the black thing on the bottom of the front of my car was half way off, I don't know what it is so I drove home anyways, then when I got home it was three-fourths of the way off. I needed to run an errand & by the time I got back it was all the way off & I don't know where it is. Does anyone know what it was & how important it is to have on there & if it's ok to drive my car around? My little brother keeps telling me that my car is going to fall apart without it is this true?It's a 2003 Honda civic LX 4 door.It wasn't the bumper it was a plastic thing underneath the bumper.
