Found what looks like an old opened out coat hanger hanging out of the passenger side underside plastics, heard it rubbing on the road....it's nothing of the car is it?.... Haven't a clue how it got there, owned 13 years and never noticed it before and mot'd last week. It's like something you'd use if you were locked out?
