Just read this article and it states that the Hot Wheel Haulers will be making a number of appearances as part of the upcoming Snake & Mongoose film. A few of those appearances will be at a couple of Barrett Jackson Auctions. With their final appearance @ the Barrett Jackson in Scottsdale where they will be auctioned. I am sure they will go for a pretty penny, I would hate for these to be bought by some private collector to go unseen by most though.....

"In conjunction with the Hot August Nights Auction Presented by Barrett-Jackson, on August 8th Hot August Nights, Barrett-Jackson and Snake and Mongoose will present a concert with Capitol Records’ Jack Dempsey, whose music is featured in the upcoming feature film.
The producers of Snake and Mongoose will also host a star-studded, red carpet premiere of the monumental movie on August 9th at the Century Parklane in Reno, where the legends themselves are expected to attend.
"This is truly an epic event to have partnered with Barrett-Jackson and Don Prudhomme, combined with the week long Hot August Nights activities to promote the first Hollywood movie about drag racing legends since 1983,” said Tony Marini, executive director of Hot August Nights. “For the hundreds of thousands of car enthusiasts who come to Reno for this festival, they are sure in for a once-in-a-lifetime treat in which they get to witness these iconic cars first-hand."
After Reno, the Hot Wheels Haulers and Funny Cars will continue on their journey and head for Detroit, where they will be unveiled in the parking lot of the Palladium 12 - Downtown from August 13-18, 2013 in conjunction with the Detroit Woodward Dream Cruise. From there, they will head across the country to Indianapolis to be displayed in conjunction with a benefit screening for the Leukemia and Lymphoma Society on August 29th before being displayed on the grounds of the Indianapolis Raceway Park during the NHRA US Nationals August 30 - September 2, 2013.
Following that stop, the haulers and cars will move on to the flashing lights of the entertainment capital of the world, Las Vegas, so they can be displayed at the 6th Annual Barrett-Jackson Las Vegas Auction at the Mandalay Bay Resort and Casino, September 26-28, 2013.
The final scheduled stop for these authentic cars and haulers is in Scottsdale, Arizona in January, 2014 where they will be auctioned off during the 43rd annual Barrett-Jackson Scottsdale Auction in front of a worldwide stage.'
