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

I bought my 73 Duster from an out-of-state state trooper. He told me he never really drove it much. When the insides were torn out under the dash there was some weird wiring that went back to the trunk. The connectors sure looked like computer or com gear connectors. Maybe he was telling the truth maybe he didn't drive it much. Maybe it just sat around for long periods of time. :)
