yeah lift up the car a little then check all 7 clips underneath (mine got 7) since you dont have mud guard so just those underneath will keep them tight.make sure all the clips and screws are in and tight. six underneath, two or three in the wheel wells (been a while since i took mine off). search 'removing skirts' or something along that line.
3700 is really cheap for the car, what's mileage?
