Exactly. Due to the myriad of options they had their own 'personalities'. The sentimental side of me recognizes each car not only as something a human built by hand but a car that somebody took to grandma's for Christmas, went on vacations, made out in at the drive in and 'used' to its intended purpose. They are almost like a living entity to me. Now, they are 'dead' never to exist again. Keeping the tag is an acknowledgement a specific and unique car existed at one time and had an impact on some ones life.
The history and research buff in me likes them because each car gives you an insight into how and when things were done. Each tag is a piece of a really, really big puzzle. If you put a bunch of them together, you see patterns and reverse engineer what happened, how it happened and when it happened.
Sorry to steer the post in another direction.
To the OP. Nice find. If the tags are still on the cars, I'd sure appreciate it if you can get them for me. I'll take any DCPI 62-79 and body style.
