Abstract: A demonstrator for mounting, operating and displaying a multiplicity of automotive vehicle components comprises an open-frame exoskeleton of aluminum tubes. The tubes are in a configuration suggestive of the shape of an automotive vehicle. The demonstrator is light in weight, is easily shipped and is movable by a single person. A central compartment of the exoskeleton resembles a passenger compartment and has doorways similar in height and width to door openings of the vehicle. A front compartment of the demonstrator resembles a vehicle engine compartment, this compartment defining a generally horizontal window free of other structure of the demonstrator. The front compartment includes front wheel-well outlines defined by tube segments welded together. A rear compartment of the demonstrator similarly defines rear wheel-well outlines.
