Here's a bit of history from '68...

What did you trade in?
'63 Gran Prix as I recall.

I had a lot of 50's and 60's Pontiacs back then... two Oldsmobiles, too. I was a GM guy... graduated from GM Training School in '68 but couldn't get a job at a GM store so I got hired at Dodge City. I did front end work on Wednesday nights and a/c and general repairs days.
