1) Might have bought it from Barret Jackson. There is a '67 Coronet R/T here in BC. The guy bought it for $75,000 then once it got here tried to recoup his money. It's currently down to $45,000 on a dealership lot.
2) Maybe he just finished the restoration and is hoping to recoup some of his money.
3) Maybe he accidentally looked at the Canadian Craigslist/Kijiji.
There was a '67 Dart GT that was just restored for sale awhile ago. It sold for $40,000.
