1964 Cadillac Sedan DeVille about 16 years ago. Sold it for $500 and it would easily be worth $15,000+ now. It was straight (all the chrome was there), had a very nice stock interior, the vinyl top was in great shape and it ran well. I rarely drove it so my parents made me sell it. I got it for free from my auto shop during my senior year. It was donated, I called dibs and did some work to it so it was mine. All it really needed was paint and to all the maintenance shit on the suspension gone through.
