My friends have one, they love it. They even belong to a club and have occosional meet ups. From what I remember them telling me, they were designed by Aircraft engineers in the 60's after they were layed off. The overall design is very areo dynamic and features a 455-powered front-drive Oldsmobile Toronado V8. The rear had 2 sets of wheels, which have auto leveling air suspension. The low to the ground stance makes for easy entry. I believe they came in two different lenghs, constructed of fiberglass shell on a frame. Rad names like Palm Beach or Sequoia blazened on the sides. All in all they seem like they were way ahead of their time...
