Today, I learned that if a meteorite hits your used car, it might be your lucky day.
"In 1992, a 12.37 kg meteorite hit Michelle Knapp's newly-purchased $300 1980 Chevrolet in Peekskill, New York. She sold the car to a meteorite collector for $25,000."

Then I saw this picture today… and it clicked.
