I've always known that my MM was early (see VIN and build date in my signature), but here is a piece of documentation I recently found with my car's papers. It was in the glove box when I picked up the car (w/ 6500 miles on it) from Varsity L-M in Novi, Michigan:
These are two sides of the same card, and it shows that my car was a test vehicle which was eventually restored to factory specs by DST Industries of Romulus, Michigan.
Anyone else have or seen one of these?
