According to the GM paperwork, my black 1969 was born on Oct 4, 1968. My Dad then bought it as his first new car and it became my first car in '84 and I still have it.
Here's a little video I made... if you have a chance, please give it a "Like" and ideally a "susbcribe" (I don't make many videos, you won't be inundated!) so that it maybe stays visible on YouTube for a few days!
