Oh, I've seen that story, and a good one indeed. Yes a great find.
However this is not the "Holy Grail". It is merely a rare find--a highly if not all original, never wrecked, never re-painted Pagoda.
The Holy Grail is what some people look for, and is, this SAME CAR with a "wrecked engine", that is being "given away" at a low price.
It is hard enough, as Brian Peters conjectures, to find a car with a body in this unwrecked, untouched condition. But to add "mechanical problems" and then a give away price because of them, well that is the Holy Grail. Everyone seems to be afraid of body work but willing to tackle an awful lot of mechanical work. I can tell you from having to deal with both, that work is work and it all costs money.
If Brian got the car for $2,500, well perhaps that is the Holy Grail. However, with the seller holding $20K in service receipts, I'm not sure that happened...
I can tell you this with certainty: if he did get it for a song, or very cheap, he would not have been concerned about a gummed injector pump or a transmission that needed a rebuild!!!
