I remember filling up my car at the local EZ-GO not long after I bought it, Premium was 75.9.
At the EZ-GO at the other side of town there was a Vanishing Point look-alike white Challenger R/T sitting there for a while with a For Sale sign on it, IIRC it was around $800. It was a 383 4 speed, missing a fender and the aircleaner. It was a little tired looking, but I was sort of interested because the interior was mint and my T/A's seats were ripped up and I wanted the seats out of it to replace the ones in my car.
Some clown from my high school ended up buying it for $600, and not long afterward dropped out of high school. Then I heard from a guy from his neighborhood that this clown's "friends" had smashed the windows out with a baseball bat. I went by his house looking for him to see if he'd sell me the seats, but neither he nor the car was around.
