The auto caddy of the present invention may include a main housing having one or more receptacles for holding drinks or other items, and may include one or more attachment members having one or more sets of openings through which a vehicle headrest seat post may extend on installation with two points of contact, which may increase the stability of the auto caddy, especially during sudden movement of a vehicle. The auto caddy may include optional components for subdividing receptacles, one or more hooks from which a tray may be suspended, a strap for securing the tray, and slots for suspending a trash receptacle such as a plastic grocery bag. The auto caddy may also include offset sides for manufacturing cost efficiency, in which case offset washers (which may be hook-shaped) may be used at installation to maximize vertical and horizontal alignment and stability of the auto caddy.
