That's sad. 40 years with the car and it's gone. Probably in a container headed overseas by now.
I had one car (66 Dart) that was taken for a test drive and not brought back. I found it a week later and drove it home. The guy that took it turned out to have some mental "issues". He actually called me a few days later and asked to borrow the car. A couple years later I ran into him at a local body shop... He was trying to sell the owner something and he actually turned to me and said "This guy knows me, he'll vouch for me". It got real interesting at that point and we'll leave it at that.
A friend had a 67 GTX stolen. He thought it was gone and then he saw it out in a little town... He chased it down and got a plate number and called the cops... They recovered the car... It had been painted and the VIN replaced. The paint job was better than what was on it and the car had a couple things fixed. This was in the 70's and he still has the car.
