There are tales of people renting a '66 GT350H on a Friday, racing it over the weekend and returning it on Monday. I've even hear some stories about people renting these cars and pulling the drivetrain out and putting it in another car to race over the weekend; and another tale about a car being returned to Hertz on Monday and they found weld spots under the carpet where a roll cage had been installed over a weekend to race.
Like the '66 GT350H's before them, these cars will be instant collector's items when Hertz is done with them. However, this deal is somewhat ironic, given the fact that Ford recently sold off Hertz.
Hmmm... here's another thought: There was a Shelby Dakota back in the day... Maybe the Ol' Shel could work his snake-charmer magic on the new Sport Trac since the SVT Adrenalin is dead. Ford and Carroll Shelby, are you listening???
