Ford has existing Heritage Fleets in the U.K., Germany and Australia. Over a year ago, company CEO Jim Farley charged Ryan with curating a U.S.-based collection. The American fleet now is 175 vehicles strong, with about 30% of it on display at the world headquarters.

For the first time, Ford Motor Co. has unveiled a collection of historic, concept and other vehicles long under wraps as part of a new Heritage Fleet.
