GM's Futurliner bus
This 1950 General Motors Futurliner bus, one of three remaining survivors of 12 originally built, was the top sale at Barrett-Jackson's 35th annual classic car auction in Scottsdale, Ariz. Used as part of GM's "Parade of Progress" touring exhibit of the 1940s and '50s Motorama shows, it sold Saturday for more than $4.3 million (including buyer's premium).
Barrett-Jackson expanded its auction tent for 2006 to accommodate more spectators. The 120,000-square-foot main tent is the largest such structure in North America.
