When I pulled the dash pad in my Barracuda I found a couple of roaches that missed the ash tray.
Being a mechanic all my life I've found some strange things while disassembling customers cars. Guns...money...drugs...food...jewelery. The best? It happened about 20 yrs. ago when I worked for Porsche-Audi. I had to remove the door panel on a Porsche 944 to change the window motor. When I seperated the door panel a few pictures fell out from behind the door pocket. They were pictures taken on the family's boat, including a picture of the wife topless out on the ocean.
The entire shop had to take a peak at both the picture, and customer, when she picked up her car.
