Bought a '68 Dodge wagon from an older couple back in the 90's. I had previously bought a '63 Plymouth wagon from them, and like the Plymouth, everything in the interior was covered in clear plastic when it was new. The Dodge was his car (the Plymouth hers). He had moved the rear armrests to the front doors so he could put change in the ashtrays. I was pulling the armrest off the driver's door to remove all the plastic and under the ashtray was 2 $100 bills from the 70's folded up. I went back to give them back to the couple and she said, laughing, "I knew he always hid money from me!" Sure enough, it was his stash and he had long since forgotten about it. They were a funny couple.
