Yes, it's right now, June 18-20 1982.
And I was there. At this very moment back then, I was waking up and making some breakfast, before reporting to the grid where I was an SCCA-licensed Pit Marshall. I spent all of my time during the 24-hour endurance race working with both Mustang SVOs as well as walking around the track taking pictures and observing the SVOs in competition. And, based on what I saw there, making plans to buy one once they came out (which Ford, sadly, delayed until 1984).

And think today, again, about the special and unique effort Ford put into this car. There hasn't been anything like it since and there likely ever won't be again.
