National Geographic Channel, FOX Sports 1 and FOX Sports 2 are set for 21 hours of live and same-day coverage from this year’s 12th annual Barrett-Jackson Collector Car Auction. The multi-platform, interactive broadcast begins Friday, April 11 at 12:00 p.m. ET on FOX Sports 2, continuing on FOX Sports 1 at 3:00 p.m. ET.

Last year’s auction totaled nearly $21 million in sales; with $1.8 million raised to help numerous charities. This event is one of four Barrett-Jackson auctions; and Palm Beach annually sets the tone for the collector car industry’s spring marketplace.

“At the 2014 Barrett-Jackson Palm Beach Auction, the docket of cars we will auction is the largest ever,” said Craig Jackson, Barrett-Jackson Chairman and CEO. “In each of the past 11 years, we have seen better cars and greater attendance at Palm Beach, and so we continued to increase our East Coast presence. This year is no different, with some phenomenal vehicles crossing the block at our lifestyle event, which makes for an exciting auction weekend.”

Interactivity for this year’s Palm Beach Auction includes the Barrett-Jackson ‘Social Garage,’ FOXSports.com’s multiple live-streaming cameras and the popular Hagerty Fantasy Bid Game, offering the audience an opportunity to score overall, daily and per-car prizes.
