My favorite is the "G.M. self emptying ashtray"
Part number 983817
It mounts on the vent window.
When you open the vent window the ashtray swings out and emptys it self.
Never saw one in real life. I only have a copy of an ad from the 40s/50s.
Not sure if it was really a factury ad on. The ad says "Americas finest genuine GM Accessories"
