I can't imagine doing work that poorly on such an expensive car. First of all I would have used rivets if anything and I would have gone so far as to line up the holes with a straight edge and measure them out, I can't believe that he would use wood screws and screw them in randomly like that.
And there was actually glue seeping out. And he didn't try at all to take the waves out of the side skirt, no one even mentioned that. Sh*t, at least spray some slick sand and block it for a few minutes. I hope that guy gets sued.
