Over the past few years, SPEED TV has encouraged classic car fans to head to the Barrett-Jackson auction, tempting them with the Hagerty Fantasy Bid contest. This is where viewers compete to guess select vehicles' sale prices with prizes awarded to those who accumulate the most points. This time around SPEED have sweetened the deal by offering a customized 750hp 2011 Shelby GT500, which has been upgraded from 550hp courtesy of a
Ford Racing supercharger system.
