Very cool Paceman!
My car was sold in Pampa, TX and the dealership is still in business also. Several years ago, I visited the owner who took over management of the dealership from his dad, a friend that was a year younger than me in high school. His dad was in the office and we got to visit about the car, but neither had a clue that it was anything special. They let me go into there archives to hopefully find the original dealer paper work, the records went all the way back to 1970. The dad told me a few years earlier they cleaned house and threw the really old stuff out.
I did however find a box of NOS chrome dealer emblems from the time which they gave me, so I did score something.
