I got an interesting email back from the owner of the Bewley City Garage Car Museum in Greeneville TN
The sister of John Delorean's first wife lives in Greeneville. She has given us the two leather chairs from his home office, one of his golf trophies, and several newspaper articles and photos of his first marriage. The chairs were custom designed for his 6'4" frame with leather he obtained from Packard when he left the company.
Also the Delorean mileage is only 726.
His first wife was Elizabeth Higgins, per wiki, and I think he worked at Packard from 1953-1956.
