Also, I thought I'd share one more picture.
The car was originally sold in Massachusetts. Two years later, it was traded in to the same dealer. The second owner had the car into the 2000s. I believe the third owner repainted it and had the engine rebuilt. I'm number 4.
I have a fair bit of documentation from the second owner and know he was an attorney who lived in Illinios. There are several Cornell University stickers on the car and when I looked up to Cornell, they do in fact have a law school. My hunch is he bought the car as a young man when he was going to law school at Cornell and, after graduating, moved to Illinois where he kept the car for many decades. I believe he passed away right around the time he sold the car. He must have really loved it because it's been well cared for and I don't think it's ever been outside of a garage. Kinda cool to find out a bit about the previous owner and the car's history.
I keep the original filed away in a safe place but I made a copy of the original invoice and laminated it for display on cruise nights and such.
