Quoted from o-din:If they have any questions about how a pinball machine works, they get scratched off the buyers list immediately.
I know Pinsiders hate car analogies, but after reading this post I just have to mention this.
I put my 1987 Pontiac Fiero GT up for sale in 2016 (owned since new - 63K miles on the odometer).
The first potential buyer looks her over and gets a test drive.
Then I popped the hood and trunklid for him and he asks, "Do all Fieros have the engine in the back?"
