The car, a one-off 1955 Lincoln Futura concept car, was sold by Ford to George Barris, who modified the car for the series. Barris basically stole the car, and made a mint on it. The car cost $250,000 or $2 million in 2009 dollars, but Ford sold it to Barris for the nominal sum of $1.00 and "other valuable consideration."
Way back on Nov. 29, 2012, Barris Kustom and George Barris had announced that the Number One Batmobile was to be sold at the Barrett-Jackson car show and auction held in Scottsdale, Ariz., which it was on Saturday.
The final sale price after was $4.2 million (before buyer's premium). There was, it was said, an intense amount of bidding before car collector Rick Champagne from Auwatukee, Ariz., won the prize.
Barris' publicist said his client is pleased with the auction result, and who wouldn't be? For $1 in cost (basically), Barris made about $4.2 million. Holy income tax, Batman!
