Not as good as some of these, but in my early Navy days, a guy had bought a Geo Metro (all he could afford). Me and 3 others picked up the front of the car and walked it to a different parking lot. Same car had a sun roof that he left open so we filled the car with Styrofoam peanuts. I have had the leaking
oil trick played on me, but I did an inspection before panicking so it backfired slightly on them.
