The Carpool Deville — This vehicle gives a whole new meaning to the term "carpool." Engineers Duncan Forster and Phil Weicker converted a Cadillac DeVille into a working hot tub on wheels. According to Forster, "You haven't really lived until you've sat in a hot tub and watched the world roll by." Photograph by Jeff Newton
