Got it new in '68. Picked it up on May 23/68. Have the original hand written invoice as well as the printed out invoice. Found the build sheet behind the glove box. Have the owners manual with the certicard in the back.
Used the car for my job as a service tech for a few years then got a beater and used the cuda after work and on weekends.
Didn't use it much in the late '70's and on. It sat in my father's garage for 20 or so years. I would register it every now and then but it was a pain to keep going to my folks place to get it so it mostly sat until my family and I moved and we had a double garage built and I could bring it home. Now it is registered every year. My wife and I go to car shows with it. It is all original even the paint. I added some options that I didn't get when it was new but they are all nos pieces bought back in the day.
