For every perfectly preserved, eight-figure collector car that surfaces at Amelia Island or Monterey, there's a vehicular treasure that's stashed away for good, never to be seen or enjoyed by the public again. While it's clearly different from a pre-war Bugatti, my mind goes to Ford's experimental turbine semi-truck named «Big Red,» which was hidden for years until my old coworker Peter located it. Something in that same vein is happening in New Jersey right now as the last surviving Mack M100SX, the largest truck ever built by the manufacturer, is being restored after decades of disuse.
