1978 Ford Fairmont. That was in 1990, so the car was only 12 years old, and it had no damage, but it felt OLD to this teenager at the time.
DD's first was the 2003 Grand Marquis I mentioned in the original thread. It was about 12 years old when she first got the car and it's still going strong as it edges toward 20 years old.
DS's first was a 1996 Toyota Corolla. It was 20 years old when he got the car. It only cost us $600 and we put another $400 into it (it had been sitting for about a year when we bought it). He got rid of it last year (gave it away to a friend in the Air Force who is still driving it) when he got himself a newer model of the same car.
