People hang on to things for sentimental value. There is a guy by my place here that has a 66 Caprice 2 door coupe that will NEVER let it go because it was his son's car. It sits alongside his garage. His son was killed while riding a motorcycle. The countryside is full of cars that people just will not give up for whatever reason.
This car is in Great shape..the owner has had it for 15 years just sitting in the same spot.
He pulled the tranny and the 455 and is one day going to fix it up..you know..the usual.
