Well lets see-
My brother bought a 72 Malibu and also did the radio replace and in doing so found a quart sized bag of "white powdery stuff" which we gave to a friend for $50, later this freind was sporting all kinds of new stuff
2 of my old cars had used condoms
crammed underneath the seats, therefore from now on any used cars now go to the local detail shop. Various other things -tools, money, food, and my current car 92 legacy had fireants from a visit to Georgia that decided it would be a good time to "come out" whilst on a return trip back to Tennessee
