What stuff have you found in your cars from previous owners?

When I bought the 72 Dart Custom 4 door, the driver side front fender and under bumper fascia were beat to hell.
Within a few days I drove it from Chicago to just beyond Cincinnati into Kentucky.
As luck would have it, a major exhaust leak developed in SE Indiana.
Ohio state police sitting at the border took one look at me coming and wasted not one second pulling me over.
I explained I had just bought the car a few days before, and was on the way to a service call job, while the second trooper had a quick look through the car.
This was very late at night.
When I had a look around inside a few days later to see what the previous owner owner had left, there were marijuana seeds and a tiny roach in the ash tray.
I was more than a little upset, but very thankful that I had not gone directly to jail that night!
