I talked to Tony P. 12 months ago when he had it for Sale on Ebay & remember when it was at Russo-Steele at Az. in January w/25.2 miles.
He told me the Original owner removed the A.I.R. system soon after taking delivery.Brought it home for his wife,she drove it around the block a few times,then parked it.She just hated it.Remorseful,they let it sit before selling it to another,who saw it as a Future collectible,while in storage,he was offered big money back then to sell it to another who saw it as a collectors item too.
Tommy Brooks was the second owner,Rick Walters was the third.
When Tony Pate got it,the Drivers side door would not engage so they had to remove the doorpanel to free it up,& found another buildsheet behind the panel.
An original correct date coded A.I.R. system was recently put on.
