Theses car are only worth it . Because the rest of them are worthless piles of rusted junk.
If the everybody kept their so called classics in perfect shape they would not be worth much.
My father had alzheimers. On his last visit to Hershey car show with his sons he had to be watched carefully that he not wander off. We walked into one car display, and dad said, Son, you will never see a car like that again in your life. The owner soon walked over, and in discussion, told us his was the only one in the world he knew to exist, and only several were ever made. My dad knew cars. Did restoration upholster for about 65 years.
