There have been a variety of cars that presidents have used over the years. Back in the 1960's Fiat
presented LBJ with this Jolly. He liked to take guests on the tour of his ranch in style. He also liked
to pretend a car was out of control as it rolled into a lake on his property while his guests would panic.
Of course they didn't realize they were driving in an Amphicar. For a picture of his Amphicar and
other presidential rides - http://www.nps.gov/lyjo/planyourvisit/presidentialvehicles.htm
