Classic car enthusiasts worldwide have been hearing rumors and innuendo.

Auction houses are on notice.

And now CultureMap sources have confirmed that the John M. O'Quinn Foundation has quietly decided to liquidate the late attorney and philanthropist's legendary car collection. The maintenance staff has been reduced to a skeleton crew, and according to reports some vehicles have already been sold.

The collection sometimes stretched to over 900 cars and was valued by some observers at over $100 million. It included many Duesenbergs, the 1911 Rolls-Royce Silver Ghost featured in the film Titanic, John F. Kennedy's 1962 Lincoln Continental Bubble Top limo and a 1937 Bugatti Type 57 Atalante. He also owned the Batmobile used in the filming of Batman Forever, a 1941 Packard limousine used by President Franklin D. Roosevelt, a 1938 Talbot-Lago, a 1938 Town Car used by Pope Pius XII and a 1975 Ford Escort GL once owned by Pope John Paul II.

AutoWeek has reported that RM Auctions has secured over 200 of the O'Quinn cars for auction, with the possibility of more later in the year.

"Fifty-five cars from the collection will be sold at the RM auction on March 13 at Amelia Island, Fla. Another 150 O’Quinn cars will cross the block March 26-28 at the RM event in Fort Lauderdale, the auction house said. Proceeds will go to the O’Quinn estate. Many of the cars will be sold at no reserve, RM president Ian Kelleher said."

Representatives of the John M. O'Quinn Foundation did not return calls for comment.
