One of the featured vehicles at the 2015 Barrett-Jackson auctions in Scottsdale was a 1950 General Motors Futurliner Parade of Progress Tour Bus from the Ron Pratte Collection. Only 12 of these were made with just nine surviving — and only three of those are in running order.
Pratte is donating the proceeds from this bus to the Armed Forces Foundation (AFF). Many active duty and veteran military personnel were present for the auction. The winning bid was $4.1 million. An additional $650,000 was raised by donors at the event to support the AFF.
Below you can watch an interview discussing the Parade of Progress Tour Bus and then a video of the auction itself.
