Is This GM's Rarest Car (can anyone confirm, true or false)

The following was sent to me, and I am happy to get any feedback as to wether its true or false.

IS THIS THE WORLD'S RAREST GM AUTOMOBILE

This is the Oldsmobile car that in 1954 could have 'killed' the Corvette. When Chevy was developing its 6-cyl. Corvette sports car with its 2-speed "powerglide" transmission and side curtains, here was a sports car from Oldsmobile with a big old V-8 and power windows. So Chevrolet, being GM's big sales and profit division, campaigned to GM to 'kill' this car. So GM said no to Oldsmobile on building this car. The world's rarest automobile: a 1954 Concept Oldsmobile Rocket F88 - the only one in existence. John S. Hendricks, (Discovery Communications founder) paid in excess of 3 million to acquire this 1954 Oldsmobile F-88 Convertible Concept Car. After spending decades as a collection of parts stuffed into wooden crates, the F-88 was reassembled. In 1954, the F-88 was a Motorama Dream Car, and was one of only two, or an unconfirmed possible three, ever created. The F-88 seen here is literally the only car left of its kind, and was sold to John and Maureen Hendricks at the prestigious Barrett-Jackson Auto Auction in Scottsdale, Arizona, for an unbelievable $3,240,000. This acquisition made automotive history and is in the cornerstone of the Gateway Colorado Automobile Museum in its own special room in a rotating display, worthy of the F-88!
