Correct me if I am wrong but on the current pictures of the car for sale I see no opening for the dickey (rumble) seat? Looks like the 1973 pictures show the dickey seat lid as well as the wind screen? Latest looks homemade and I doubt it would be worth even the price of regular car. The whole thing looks homemade to copy something someone saw. I find it hard to believe this would be historically significant and at best a curiosity.
